All observers will have seen satellites fading in brughtness as they encounter the Earth's shadow. However on Saturday (NOT Tuesday as stated by Sky & Telescope) October 12, there will be a comparatively rare chance for an observer suitably located in the Arctic circle :-( to see some satellites affected by the shadow of the MOON. The axis of the lunar shadow misses the Earth's surface by 780 km at closest, so there is no total/annular eclipse visible from the surface of the Earth. However there are plenty of satellites orbiting at suitable heights so that they will experience a total eclipse. So here a challenge - for all programmers particularly, find one or more satellites that are going to see a total eclipse on Saturday? A helpful hint - there is a series of Soviet/Russian Store-Dump/Ferret satellites and their rockets with inclinations close to 74 degrees and revs/day=14.3 or so. These will have heights close to 780 km, so surely one or two will be in the right place at the right time. So get your databases and tracking programs whirring and see what you come up with! best wishes Russell P.S. I don't know the correct answer, so it's up to you.
