GM Frank, all
You mentioned AO-7 is in full eclipse while over Antarctica. I see the same thing on my Satpc32. However that is the ground track. From 1400Km or so high does not the satellite still "see" the sun? I encountered this issue while looking at sat to sat links.

I know it is fathers day, but I have a question for the BB'S, Can we
check to see if AO7 is in Mode A today?
I have reports from Europe that it was not heard in Mode B but my
compatriot in Europe does not have mode A capabilities.
I have been doing yard work this morning in advance of rain so I missed
the morning passes over the USA, I will be on later to see if we have
had a switch.
While during this Eclipse Cycle, AO7 has been coming up in Mode B since
May 21, 2013, I have been advised that it is a purely random chance that
it will come up in one mode or the other. There are periods of full
eclipse lasting 9 or more minutes over Antarctica and maybe this was a
random switch to Mode A.
I will be monitoring the 1852UTC pass over EM55aj84ta to see what I
copy, it is a 2 degree pass for me so it is not my best pass, any
reports would be appreciated.
