So it's fingers crossed for the Solar Dynamics Observatory, destined to help the predictions of "space weather".
SDO promises to become an exciting mission as an orbiting solar observatory with multiple high-definition telescopes has never been attempted before…
The prelaunch readiness press conference will be held at 1 p.m. EST, on Monday, 8th February 2010 from the Kennedy Space Center News Center. It will be immediately followed by the SDO science briefing, both briefings will be
broadcast live on NASA Television. Launch is set for 9th February 2010 (10:30 – 11:30 a.m. EST).
Unfortunately we wont have realtime images like we have with SOHO
At 130Mbps - we'd struggle to keep up, and to establish and maintain an internet server platform to host that content would be an epic, and expensive challenge.
That's a couple of Petabyte's per annum once you factor in the need to keep the raw data and have the space for a couple of derived products for each image. Even if they decide to release jpg's in a manner similar to the MER releases we won't be having a Midnight Sol Browser downloading all of those to our PC's anytime soon.
One per hour would be ok
nprev,
I think you are going to love SDO as well. I watched the pre-launch science briefing this morning, and it is a damn powerful observatory. And of course we will still be getting data from STEREO.
I think we are going to learn a lot about our nearest star.

So when does the mission officially begin? They've launched successfully, and have to maneuver into a better orbit, but how long until the firehose opens up? I hope they follow the HiRise team's lead....
April I think
Hmmm. The SDO Mission website is down. I hope that is not a bad sign. They will probably get it back online after the holiday here.
Pertinent to this thread, one of the people on the Scientific Briefing last week commented that they were hoping to get SDO in orbit at solar minimum so they could follow an entire solar cycle. They were quite delighted that the Sun had "cooperated" by delaying its exit from minimum.
BTW, the briefing materials are http://www.nasa.gov/mission_pages/sdo/news/briefing-materials-20100209.html. There are some pretty cool graphics there.
"It will take about 3 weeks to circularize SDO's orbit and another month to test the spacecraft and check out the science instruments. We will see first light in about 60 days"
From a new blog post on TPS. Doing well so far....
The http://www.planetary.org/blog/article/00002346/ blog was written by fellow Solar System Ambassador Ken Kremer and is certainly worth a read.
SDO is being described as "the crown jewel" of Solar observatory missions. As part of their outreach, National Air and Space Museum (and another museum whose name I don't remember) will have big flat screens showing the near real time images of the Sun. (1.5 terabytes/day will be coming down to the ground.)
You know, I think we are going to need an SDO thread.
SDO website s back online with news that on February 17, 2010 the observatory completed the first of 9 main engine burns that will raise the spacecraft from 2500 Km into its final geosynchronous orbit at 36000 Km...
SDO is on Station
Tue, 16 Mar
The third Trim Motor Firing (TMF #3) was successfully completed Tuesday evening. This apogee burn raised our perigee to geosynchronous with an orbital period of one day.
SDO is on station, next is to start up the instruments!
For part the way up, one channel of the EVE instrument was on. All the doors and filters were closed, though which means that its measurement was uncorrupted by light.
Every time the spacecraft went through perigee, the signal on that channel spiked by a factor of 10. The first perigee was less than 1 hour after we turned the EVE electronics on. It was kind of scary watching it the first time, wondering if it would ever turn around. We recognized almost immediately that we were seeing the protons of the inner Van Allen belt. Our instrument is relatively well shielded against the electrons of the outer belt, but we could (just barely) see that belt also.
Now EVE is an ultraviolet instrument, not a radiation instrument, and is not calibrated to do an actual radiation measurement. We can't say that a particular measurement represents so many particle hits per second, particle energy, particle type, or really anything other than we got higher counts here than there. But it does make an interesting map.

SDO isn't taking the same sort of imagery as the instruments mentioned in that article.
http://sdo.gsfc.nasa.gov/mission/project/leostatus.php
They've reached science orbit and are testing instruments now. Encouraging to see that they're posting on weekends...
First light is expected very soon
HMI door open. Sweet.
EVE instrument: All four doors open, all channels are functioning properly
Heard at the UK Space Conference, a STEREO scientists wouldn't comment directly about SDO when asked if he had seen pictures yet - but he said "I'm smiling"
I think they are opening the doors to the AIA instrument today.
All 4 doors on the AIA instrument successfully opened a few hours ago.
First Light press conference tentatively scheduled for 21 April 2010
From SDO's Twitter updates:
"First Light press conference scheduled for April 21st! Calibration tests so far are amazing. Updates here: http://ow.ly/1uKgs "
Not building these images up at all, are they?
Massive solar prominence

Unfortunatey, it looks like SOHO missed most of the event.
I wasn't sure what I was going to write about today; that'll do nicely! Thanks for keeping an eye on the Sun for the rest of us, Sunspot! I would love to see SDO images of this; I don't yet have a good sense for what SDO will be showing us.
Im soooo hoping SDO caught this... can you imagine it not in a 1024x1024 pixel image like SOHO but one at 4096x4096 and images every 10 seconds
Made a animated GIF from the C2 images
SDO started a calibration maneuver at 8:00UTC during this event, in which it turned away from the Sun. During the maneuver it would have briefly glanced at the Sun again. This was after the EIT image mentioned above, but before the coronagraph images. I can't say anything about whether AIA was taking pictures before 8:00, just what the spacecraft as a whole was doing. If they were taking pictures before this maneuver or during the part where the spacecraft glanced back, they should have something (additional) awesome to show at the first light press conference.
It's not like this is the last flare expected to occur during SDO's lifetime. There will be dozens, hundreds, thousands over the next decade.

http://soho.esac.esa.int/data/LATEST/current_c2.mpg
(interesting to see something apparently flying splat into the Sun on 10 Apr - I assume this has been discussed elsewhere)
No, not at all. IIRC, SOHO's picked up more than 1700 Sun-grazing comets, many of which actually impacted the Sun.
Relatively bright ones like this are uncommon, though, and definitely very cool!
All this activity is really making me want to buy a solar telescope... Had a look through a few, and seeing prominences in an eyepiece is absolutely amazing. I think that once SDO starts releasing images, and video, of the Sun "in action" demand for solar telescopes is going to go through the roof...
I feel some overtime coming on...

An extra link from a friend:

I have reason to believe there will be some incredible videos posted there.
The SDO Outreach team really seem to have a handle on it, don't they? I think this will be a brilliant and very rewarding mission to follow - and that sales of solar viewing telescopes will rocket after tonight.
Or people might go ( like I did a while ago ) "Meh - not much point looking through a telescope with pics like this available"
Yeah, but then they actually *look* through a telescope, and see the prominences leaping off the Sun with their own eyes, and the Sun becomes... alive... I'm hoping to get a solar telescope set up at our solar system scale model in August - and planning on some big summer overtime to afford to buy a Coronado for myself, too :-)
Presser now starting on NASA TV.
Umm.
WOW
As "Lika" said, "... struck with awe."
I only attempted to download one, but didn't have a problem.
If it weren't 40 Mb I would e-mail it to you.
I was poking around the SDO First Light web page and I found this site. Has the movies in numerous formats and sizes.

Mindblowing.
SDO might just be the mission that finally converts Mrs. nprev into an UMSF fan...just caught her independently surfing to this site on her MacBook!
Just stunning.
Like MRO/LRO all over again!
Quite a trio we've got going on eh?
No worries. She married a sleazy cigar-smoking robot, she knows the score.
I wonder why they didnt go with the same colour scheme for the 304 (orange) ,171 (Blue) and 193 (Green) lines like those from SOHO and STEREO.
Here's the SOHO EIT 171 image taken at about the same time as the SDO 171 IMAGE, the difference is staggering.

On the press conference and EVE instrument:
The solar image on the EVE spectrum image is not a mistake. We designed the instrument almost from the beginning to use an otherwise unused portion of one of the spectrometer CCDs as a pinhole camera - we call it SAM, the Solar Aspect Monitor. SAM has its own hardware including a precision 26 micron pinhole, filter wheel, and its own optical path with a door (one of four on the instrument) that we had to open to get first light.
The unexpected thing about it is that we are able to see the sun as well as we do. The SAM image was apparent in the very first CCD image we got down. We weren't expecting to be able to see the limb or active regions this well until years from now, well up into solar max.
-- A concerned EVE data processing engineer
V cool...
"SDO shows Earth eclipsing Sun":
http://www.youtube.com/watch?v=TjlFL-3rLLE
Those comparison images really drive home the difference in resolving power.
The comparison between MRO taking on MGS's role is more and more apt!
Come on, you knew it was coming...
http://astropoetry.wordpress.com/2010/04/23/sdo-opens-its-eyes
Yeah, the way it was worded made me think it was a problem too.
Perhaps I missed the information within thread... do we have any indication of public, regular, real-time images release in the next future???
SDO Day 76: Getting Ready for Science Data
Mon, 26 Apr
SDO is moving toward becoming an operational science mission. The data will be available from several sites in a variety of formats. SDO scientists and engineers are working to set up those access points, but we won't be ready for regular data releases until mid-May.
Next step is the EVE calibration rocket, scheduled to fly on May 3, 2010 from the White Sands Missile Range.

Now that we have "real-time" images of the sun, I've been wondering about the issue of light-time delay:
In these images, do the scientists need to take into account the light-time travel distance between different parts of the sun?
For most planets, even Jupiter, it doesn't make much of a difference. But the sun is several light-seconds wide. (Ah, "about 4.643" in diameter from a quick Wikipedia lookup.) The sun is a globe, so if dead center of the image is "now", the edge of the images would presumably show events that happened a few seconds "before" the center's events--in other words, no picture of the sun shows it all "at the same time"!
Would this effect distort the shape of prominences? (I mean really big ones.) Should we "correct" images for it? (Leave the center alone, but shove the part at the edge back closer to the sun so "the is the shape it really was at that moment"?)
Maybe we should mentally overlay an archers-target of concentric rings over sun images: label bulls-eye as "now", the next ring as "x sec. ago", etc.
Can we fix this? Merge pictures taken a few seconds apart: keep the center and merge the outer part from a few seconds before it... Oh darn. It only takes pictures every 10 seconds. Missed the window! But you know what I'm going for.
What is the way solar scientists handle this issue?
I would imagine that since not a lot of things occur in a 4-second duration on the sun, compared to what all is being observed, it's forgivable.
But I'm not a solar physicist so that's just my uneducated guess.
The scale of observations should be considered. Phenomena of interest such as prominences, etc. are fairly localized, so the speed of light isn't really much of a factor. In any case, events that might effect the entire Sun (i.e., long-period 'seismic' oscillations) obviously propagate at far less than the speed of light, so again SOL lag isn't really a consideration for observation or interpretation.

Oh man, like my hard drive wasn't groaning already...
VERY chuffed - and honoured - to have my "First Light" poem featured on the SDO Website...
http://sdo.gsfc.nasa.gov/mission/project/leostatus.php
Well done, Stu!
http://sdo.gsfc.nasa.gov/data/
The SDO site now has access to images, although its listed as "the sun now" they are about 36 hours old.
Some fantastic magnetic loops visible in the "193" images today
The SDO images have been looking a little odd lately, not sure if its a processing issue before they go onto the web or what. Looking badly overexposed.
Maybe the sun is too bright?
<ducks>
Gorgeous pic, thanks!
I was really tthinking about buying a solar telescope, but can't help wondering "What's the point, when I can enjoy the view via SDO?" But I'm one of those people who actually finds more enjoyment and satisfaction in seeing Jupiter's belts and moons for real, through my own 4.5" reflector, than I do from looking at a Hubble portrait, so I'll probably still get one... some day...
I agree- there's nothing like the experience of seeing/imaging the Sun, Moon, or planets yourself compared to images produced by spacecraft. SDO is great, but the beauty of owning your own solar scope is you can watch changes occur on the Sun in real time. A good, small solar hydrogen-alpha scope is very affordable nowadays.
I use an old Coronado PST and a webcam to record prominences, filaments, and active regions on the Sun every day it's clear (and something interesting is visible). Here's a mosaic I took last week using this combination. BTW, the scope, camera, and tracking mount I use cost a total of just under $1000 US.
Prominence from STEREO B
http://stereo-ssc.nascom.nasa.gov/browse//2010/06/07/behind/euvi/304/2048/20100607_181615_n4euB_304.jpg
Sure Jeff-
first, I used a very short 2x barlow to increase the image scale. Had to be very short because the PST doesn't have much back focus.
I shot 9 short videos with the DMK; each were about 600 frames long. These had generous overlap between each because the PST has very uneven illumination across the field; it's not vignetting, the problem is the narrowest region of bandpass is pretty small on the PST, so I tune the "sweet spot" to be at about the middle of the image, and simply use large overlap and crop out the areas that I don't use. Also, choose an exposure that doesn't overexpose bright regions on the solar sisk and use the same setting for all your videos; this avoids problems with overlap between frames.
After taking the videos, I bring them into the freeware RegiStax and stack the best 150-200 frames per video, and sharpen them gently using wavelets.
Next, I bring the stacked images into Photoshop (or Gimp, if you prefer) and align each frame, then cut off the areas of each I don't want to keep.
Finally, because I use a monochrome camera, I colorize the sun for aesthetics. I like a yellow sun with orange/red prominences and filaments. This last step is completely arbitrary; remember the PST looks at a narrow slice of the red spectrum (656.4 nm, less than 1 angstrom). Visually, the sun appears dark red, but the eye doesn't see contrasts well in red, so thus I colorize the image to improve visual contrast.
Sunspot region 1087 looks stunning in the latest SDO images
I really hope NASA starts porting their iphone apps to the Android platform! I would love to have something like 3D Sun on my Samsung showing SDO data!
This is neat:

Stunning prominence visible to SDO right now !!!!!! 18.30UT/19.30BST
I see the SDO sight have been tinkering with the AIA304 images, much better now, showing all the fine limb detail that was completely invisible in the previous version of these images. Hopefully its permanent and not some technical blip
Does this mean the Aurora Lights may be on the way on the 15th
...or do only CME's do the trick?
Drop them a line, ask them what's going on. They're good people, VERY into Twitter for keeping Sun-watchers updated, so they'll be happy to answer your question I'm sure.
A coronal mass ejection is visible in the LASCO images.
Wow... talk about a "Tunnel of Terror"!
http://twitpic.com/2fvduu
Huh. Looks more like the "Sydney Opera House of Pain" to me...
..and the last few weeks of CMEs and sunspots wind down again...
This solar minimum is continuing; We just had a day with no sunspots
This cycle is like one we have not seen before.
Here is a latest representative SDO image
Looks like there is an active region about to come into view.
Bright comet is just entering the LASCO C2 field of view now.
Been watching it erupt, amazing sight.
keep an eye on the SOHO LASCO images now.
Wow, it's like chinese dragon over surface of Sun or fire whip from Lord of the Rings monster (in first movie).
What about STEREO images?
Correct me if I'm wrong, but if this beast collapses & produces a major flare the Earth is not in the strike zone, right? Looks like it's already rotated too far around the limb for that.

Good catch! Thanks for the heads up on that, I was at work so would have missed it if you hadn't let us know.
Is there a proper name for the cool secondary explosions when plasma falls back on the photosphere?
As seen here: http://www.youtube.com/watch?v=LpkXhlPIINQ
I dont know... I don't think i've ever seen anything like that before, maybe its just SDO is the first to be able to observe such explosions.
I've never seen that splashing either. What a cool (HOT) video!!!
Those cold gas filaments falling back and flashing up as they "impact" have got to be one of the coolest things about the Sun I've ever seen. It's like throwing sticks of wood into a lava pool. The initial shockwave was also cool.
The shockwave in the AIA 211 images is probably the most impressive it looks like an expanding bubble.
Some good gif movies on the SOHO site...
http://sohowww.nascom.nasa.gov/data/realtime/gif/
I think the STEREO AHEAD probe will have had a great view of this prominence.
Very exciting images and either very provocative
Just beyond freaking amazing. To witness such titanic phenomena is a stunning experience.
It can't possibly be safe to live in close proximity to such a monstrous thing. Somebody should do something!
Not to worry, give it a couple gigayears and the problem will solve itself.
Compared to the Earth, how massive are those "sticks of wood" referred to by Ugordan in 160?
And, where were Mercury and Messenger when the big outburst took place?
Do events like this have the ability to damage the spacecraft?
Quick comparison between size of Earth and Sun (and the eruption).

But this image, which is a composite, seems ok. weird

It doesn't look "ok" to me, I see huge data gaps in certain bands. Obviously some bandwidth/downlink issues.
This one seems ok to me though http://sdo.gsfc.nasa.gov/assets/img/latest/f_211_193_171.jpg I don't see anything on the website to say they have changed the images.
SDO following a "lunar transit" right now... GORGEOUS views...

Hi, I combine colour image from today images. I use FITS 1024x1024px AIA 304 ( R ) AIA 171 ( G ) and AIA 211 ( B )
This has got to be the most amazing image of the Sun I have ever seen.

"Last Friday the Sun put on a magnificent display, ejecting a massive solar filament that was captured by NASA's Solar Dynamics Observatory (SDO) in all its glory."
Wow, that is an awesome image! Thank you very much for posing it. Now Hollywood special effects houses have something to aspire to.
Today's http://sdo.gsfc.nasa.gov/data/ show the solar disk http://sdo.gsfc.nasa.gov/assets/img/browse/2013/04/17/20130417_144528_1024_0131.jpg, and in different locations http://sdo.gsfc.nasa.gov/assets/img/browse/2013/04/17/20130417_141428_1024_0131.jpg. I have never seen that before and I check almost every day. Perhaps some pointing issue?

PS Some stunning flares/prominences, BTW!
Looks like very ordinary, regular flat-field maneuvers. They've done them many many times in the past.
Confirmed...
Ah thanks, good to know! I guess I just never happened to look at the web page when they were doing that before.

I managed to reprocess some frames grabbed from the 13th of May, in the morning (about 6:00 AM GMT), with 131 and 171 filters .

...stunning. Can you make a wallpaper version, Damia?
Yep

A really http://svs.gsfc.nasa.gov/vis/a010000/a011300/a011385/ was released a couple of days ago on the NASA Goddard website, showing the Sun in multiple SDO filters at the same time.

Hi
I can't open FITS images from SDO. I try NASA view, Fitswork, Maxim DL and nothing
Images are from http://sdowww.lmsal.com/suntoday_v2/
and http://jsoc.stanford.edu/ajax/lookdata.html
I've just performed an animation of solar activity over a period of 24 hours on March 21, 2017 on the basis of SDO data.
Time scale: 1/4hour/second, Extreme Ultraviolet AIA171.
The Earth was incorporated at scale into the animation for size comparison.
Here is the outcome:

HI Sean,
I just thought the last days: Are there any new videos from the SDO probe? :-)
Thanks for this videos, they are really fantastic!
My hint: Just look at this video in slow motion (1/4 speed)!
Good timing & thanks!
I'm working on a long form 'filament' clip which is very pretty to look at!
Great job Sean! Wow, that June 11th video....Amazing!
Have noticed an anomaly in the Solar Dynamics Observatory daily intensitygram images, for the past four days. On the righthand side of the images there is an odd, diagonal line across the solar disk, which is lighter in color than the surrounding surface of the Sun.
I suspected this was a transitory fault, perhaps caused by the intrusion of an energetic particle into the camera. This seems unlikely, though, after three, day-after-day repetitions, in the very same position against the solar disk. It also seems unlikely that an imaging processing artifact would persist like this, without correction, or even comment. Any ideas on what could be causing this anomaly?
link?
https://sdo.gsfc.nasa.gov/assets/img/latest/latest_1024_HMIIF.jpg
It's pretty obvious in the thumbnail visible at http://spaceweather.com/ The Gong H-alpha monitoring network doesn't show anything there. http://halpha.nso.edu/
It's been two weeks, now, since the anomaly was discovered in SDO images. It's still visible in today's daily intensitygram images. The Joint Science Operations Center, at Stanford, has had, and still has an advisory, in red, at the top of their webpage. They admit that that the anomaly can not be removed by image processing, and that they can not explain the source or cause of the anomaly.
Please find a link to the JSOC website, below:
http://jsoc.stanford.edu
I'm honestly not seeing this artifact, can someone post an actual image that shows it?
The tone of some of these messages is flirting with rule 2.6 IMHO.
Here's a clip off of Spaceweather with the artifact highlighted. It's a diagonal strip across the disk.
It's faint, but I can see it in both the Spaceweather images ( http://spaceweather.com/images2018/30aug18/hmi1898.gif?PHPSESSID=of9s74qb316i687mccdvc5rrq4 ) and here: https://sdo.gsfc.nasa.gov/assets/img/latest/latest_1024_HMII.jpg
Roughly the 3 to 4 o'clock position. It hasn't moved so it must be an artifact as JSOC says.
The anomaly was much more noticeable, earlier in the month. The fact that it changes, yet persists seems possibly significant, in itself. Please find a link, below, to the SDO image from August 17th:
http://spaceweather.com/archive.php?view=1&day=18&month=08&year=2018
I'd suggest calling it an "artifact" as the JSOC does, rather than "anomaly," because the latter word means "very serious problem" to space engineers and this doesn't seem to rise to that level. It's annoying to have a new artifact that can't immediately be dealt with in calibration, but no more than that; I can't see this affecting science. I will be curious to learn what JSOC eventually has to say about what they think caused it. My money's on an unwelcome guest in the form of a teeny speck of dust somewhere.
