If the bird is in range and it's daylight at your location, then the
satellite is also in daylight.  If any part of it's footprint is in
daylight, the satellite is sunlit.  I would assume that at 11:58 your
local time (9:58 UTC), that you are experiencing daylight.

Hello Folks,
               As we all know (or assumed), AO-7's battery system has
down the tube for a couple of decades. However, this morning I got quite

I always monitor the old girl before actually *bellowing* into the 
microphone. As is my want, I was watching  both InstantTRACK and NOVA on

seperate computers (and before you comment, my keps are! correct and up
date). The satellite came up over Northern Russia at 09:58 UTC on the
orbit and was in complete darkness at that time but just for a laugh I
a few CQ's on CW (432.150 up 145.941 down) and to my surprise I copied 
LA2QAA calling CQ - (that's me folks).

Thinks ... "This can't be, the batteries are knackered".

This instigated careful checks of time (Atomtime Pro), keps & doppler -
doubt - (both InstantTRACK and Nova agreed) - AO-7 was in darkness but I
able to copy my downlink at S3. A few minutes later, when the old girl
into sunlight my signal shot up to S8.

Careful checks of my hearing and senility confirmed that both are! 
functioning correctly.

So ... how come I could hear myself when AO-7 was in darkness?. As can
imagined, I will keep tabs on this tomorrow morning.

Sensible explanations please written on the back of a clean $100 bill 
wrapped round a wallbrick and chucked through my window - or - an e-mail
<la2qaa at amsat.org> at a pinch, will suffice

73 John.
