RE: AO-40 Checkpoint this Sunday


I don't show a favorable pass next tuesday.  I just looked for MA 230-255,
nothing on tuesday.  If you look at MA 0-50 there is a pass on Tuesday, but
it's at 3am atlanta time.  or a 1000pm atlanta time.

I don't think you have something right in your prediction, or am I missing

Best MA's for telem. 230-255, with maybe some carry over to 0-15

Hey all,

Am I missing something here or is there a very intersting AO-40 pass next
Tuesday?  Looks like the attitude is the most favorable we have seen for a
while and at a reasonable hour.
