re: It could be Earth
I used my Starrynight program and set home at Airy Crater (5 degrees S Lat 0 E Long) 0h UT on Mars but Earth was 55 degrees below the horizon and would rise at 9:37am.
I guess I could have been more specific and researched the exact time the photo was taken and tried to refine a closer location on Mars relevant to Opportunity's location but...
Maybe when I have the urge to explore.
