Any hope that exceptional surface winds are more likely in these conditions? To be honest, seems like clear skies would be better, but here's hoping. We need some unprecedented weather of the beneficial kind.
We can see the effects of the elevated atmospheric dust levels in these unprocessed IDC images, that were acquired just three sols apart.

NASA will host a virtual media briefing at 2 p.m. EDT on Thursday, Oct. 27, to share new scientific findings based on observations from the agency’s InSight Mars lander and Mars Reconnaissance Orbiter (MRO).
Science team members from both missions will explain how data and images from each spacecraft – one on the Red Planet’s surface and one orbiting above – contributed to the discovery. They will share how the two missions worked together to confirm their observations. There will also be an update on InSight’s solar energy status.

Cool! Impact detected mentioned Sept 19 -- will be good to hear more.
Bonsoir,
The announcement will probably be about something other than an impact. A magmatic activity inside the planet would be even more exciting ...

Appears to be an impact.
4 to 8 weeks left, in terms of power usage, by the PI's estimate.
That's a big crater, wow (150 m)!
Ice boulders excavated!

Less than 300 watts per day, expect to lose contact in 4-8 weeks.
Elegiac comments from Lori Glaze.
Nature's Alexandra Witze has put up a good article: https://www.nature.com/articles/d41586-022-03447-4
Apparently there was an earlier significant impact in September 2021. The press conference and related release discussed only the larger impact on December 24, 2021.

InSight lander reports largest-ever meteorite strikes on Mars, and scientists wish it a fond farewell.

HiRISE image is here:
https://www.uahirise.org/ESP_073077_2155
This was taken February 27th, about 2 months after impact; since ice isn't stable at that latitude, they will eventually vanish (though obviously much more time than the tiny chunks Phoenix dug up from its trench, but the higher daytime temperature should speed the process up somewhat. Presumably there will be follow-up HiRISE imagery? They ended the presser after half an hour, obviously not enough time to get all the questions.

~285 Wh as of yesterday, which is about the level of the last precautionary seismometer deactivation.
Coming up on vernal equinox there, so I assume it's still dust accumulation that's driving the trend.

Sad news
On Dec. 18, 2022, NASA’s InSight did not respond to communications from Earth. The lander’s power has been declining for months, as expected, and it’s assumed InSight may have reached its end of operations. It’s unknown what prompted the change in its energy; the last time the mission contacted the spacecraft was on Dec. 15, 2022.
The mission will continue to try and contact InSight.

Well done Insight! These stationary landers dont get the
press the rovers do, for obvious reasons, but this mission
and Phoenix have done really important work.
It was a shame about the heat flow probe,
but next time I'm sure they will try something different.
Everything else worked a treat, and I look forward to seeing
publications coming from this mission for many years to come.
I wonder when we will next we will next see a seismometer on Mars?

Aww, that's sad.
Farewell InSight, you were an amazing but underrated probe that made Mars geologically exciting again!

I have requested a HiRISE image.
Going to try
Very good! Too bad that albedo markings may have faded considerably by now, but it may be useful.
(in case the subject of this post is not clear, it's about a dark marking I suggested might be from the InSight cruise stage impact. It appeared on a CTX image taken a few weeks after landing but was not visible in the previous image, some years earlier. But it is a bit further south than I would like it to be.)

I'm doing planning this HiRISE cycle and I just want to say how much I appreciate having the CTX image number called out and a graphic showing what I need to be centering the image on (some of these fresh impact sites can be hard to spot). So if it has faded already, at least the image will be centered on it.
I was just looking at the new HiRISE image of the "InSight cruise stage impact candidate" as the description says. Unfortunately it is about 2 or 3 km too far west and misses the feature I had described.
