Re: Calculating martian eclipses

I have a veeeery old Astronomy program (dated 1993!!!), but it is very useful to 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).

Re: Calculating martian eclipses

I recall a program, it was like a space encyclopedia on CD-rom called redshifts I think Focus media made it?

You had a star chart that would show you the planets form earth but an extra feature was that you could pick a view of the night sky from the moon and mars.

I'll see if there's a site where you can download something like this.
