Looks like they cant get pancam frames taken quick enough to do this properly
Yes it would be nice to see a proper annular eclipse.
Does anyone have any idea how common these eclipses are? I'm guessing were in an 'eclipse season' right now and they are not going to keep coming so often.

I have a veeeery old Astronomy program (dated 1993!!!), which can easily calculates oppositions and conjunctions between every Solar System object. It's named Expert Astronomer, is a commercial program, and I payed around 20$ for it
, but it's great.
I made an approximate calculation of march Martian Deimos eclipses, and I obtained these results:
(DATE time separation altitude)
2/mar/2004 9:33PM 37.2' 17 deg
4/mar/2004 3:54AM 19.1' 69 deg
9/mar/2004 5:20AM 53.0' 79 deg
10/mar/2004 11:42AM 1.2° 8 deg
I used 1.95S , 5.53W coordinates for Opportunity position, but I think they are not enough accurate, as the graphical simulation of the eclipse... actually does not show an eclipse, but just a Sun-Deimos proximity.
Where could I find a REALLY accurate Opportunity position?
How can I know the exact date/time of already happened&photographed Martian eclipses?

P.S.
Maybe AstronomyLabs, an old freeware program can also do this calculation, but actually I didn't try it ( I remember it could for Earth/Sun/Moon eclipses).
