Space Station May 2.
 

May 2 at 8:46PM the ISS will be visible for 3 minutes at a max elevation of 72 degrees. Pretty high overhead. It will rise about 41 degrees above NW and set 19 degrees ESE. Tonight you could see it for 4 minutes just after 8:21 but it was low in the sky at only 30 degrees. Oh and you can see it again tonight at about 31 degrees but only for two minutes at 9:56pm. So if it isn't cloudy out.....:D
Also tomorrow if the shuttle takes off, it too will be visible high overhead at 88 degrees max elevation at 8.57. But that is only if it takes off tomorrow.
