With Spirit producing an annoyingly large amount of power given her current predicament, the time may well have come to re-open the Gusev astronomy society. Anyone have any dusk / nightime observation ideas?

Dust opacity was actually higher then, but Earth was 8.5 deg higher in the sky for the same solar depression angle. Roughly, I get a 35% fainter Earth and actually an even fainter sky. So, more than "iffy", even thought the filters won't be as sensitive as for that image. In any case, some images are on the agenda. They are not optimized specifically for planet hunting, but they are aimed so that's a bonus (and you'll see little Earth trails...). Aside: an RGB set could be quite fun in a couple weeks when E & V are at their closest, but it will still be close to Earth's current altitude.
