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?

Sometimes the science objective requires exposures that don't help--like 10 sec L1s with 60 sec R4 or other (not to mention single eye imaging). But a common strategy is to start exposures at the same time and have one eye use a 61 sec exposure and the other use 60 (or similar 1-sec offset). So, odds are (in decreasing order) no meteor is seen; one is seen only in L1; one is seen in both with no obvious staggered end point; one is seen in each, and the end points project to different points of the sky. The last, of course, would imply the meteor was in the FOV at the end of the exposure (since start time is the same), and would show motion direction and show how much motion occurred in the last second. Low odds of success-but frequently, no cost to doing. So much of the 2005 meteor campaign used this. (generally, the right eye would get the extra second, but that's not a rule or anything.)
