I was using Satellite Safari to plan for tonight's SAC Thunderbird Star Party, and came across a couple good passes. Times and altitudes will be slightly different from other parts of Arizona. This first of these is Hubble Space Telescope, which will be 30 degrees above the southern horizon, moving west to east, at 7:56 p.m. This is only a half hour after sunset, but it should be visible, at magnitude 1.9. The second event involves two 3rd magnitude satellites moving in opposite directions that will pass within a couple degrees of each other at 8:20 p.m. At the time of closest approach, they will be very close to Arcturus. The southbound satellite is Cosmos 2242, a Soviet intelligence satellite launched in 1993. Headed northbound is the SL-3 rocket body, which launched another Cosmos satellite in 1981.
