We are back into the cycle where the ISS is visible in the evenings.
Tonight (Monday Nov 7th), the visible pass details are below:
Acquisition (AOS): 18:07 on a heading of 291 degrees.
Time of Closest approach (TCA): 18:11 on a heading of 346 degrees and
elevation of 9 degrees.
Loss (LOS): 18:15, on a heading of 42 degrees.
Some people might not be able to see this pass due to ground clutter. (9
degrees is not too high: An approximate rule of thumb: Hold out your arm
straight ahead of you. Turn your wrist so that your fingers and thumb are
parallel to the horizon. Adjust so the lower edge of your lowest finger is
sitting on the horizon. Now, the top edge of your thumb is approximately 9-10
degrees above the horizon! (In other words, the width of a human hand viewed
at arms-length is approximately 9-10 degrees).
Visible evening passes in November are on 7,10,11,14,15,17,18,19,21,22 and
23rd. Then the visible passes switch to morning visibility sometime in the
05:45-06:30 window. Morning visible passes are on 28,29,30 Nov, and
Rather than disturb everyone with regular messages to these reflectors on
this topic, if anyone would like to obtain prediction software to run on their
PCs, I can direct them to some sites. That way, you will be able to keep track
of the ISS and other objects as you wish.
And don't forget to listen on 145.800 MHz too! The ISS crew are becoming more
active on voice. One one recent pass, they spent 20+ minutes chatting on
voice, with stations in England, France and Italy. If the system is not in
voice mode, you may hear the repeater, or the packet station. Note that the
uplink frequency varies base on which mode the system is in. If anyone needs
more details on uplink frequencies, they can reply directly to me.
