I ask because my friend with the good telescope says X37B is up around 4 am California time, but that's not a good time to image it because the marine layer (fog) is dense then. ------ Ummm.. Not for the last two days or even the next 2 days.. For all things Satellite, Heavensat fits the bill..

Later the (2) Sun will rise on the current sub nodal point and later the (3) Sun will be South of the sub nodal point, later the (4) Sun will set on the sub nodal point and finally the (5) Sun will set on the satellite. Is there a graphical representation of these 5 key points? I ask because my friend with the good telescope says X37B is up around 4 am California time, but that's not a good time to image it because the marine layer (fog) is dense then. Knowing these 5 key points on the orbit would tell you not only when it would be a good time to look for the satellite but also when the satellite would have a good view of the Earth. -- Have Fun, Brooke Clarke http://www.PRC68.com _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-l _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-l
