[amsat-bb] Please do not use AO-51 while eclipsed

We've turned the repeater back on on AO-51, along with the PL. I have a 
favor to ask of our Southern Hemisphere users, including those in South 
America, Southern Africa, Australia, and New Zealand. Please avoid using 
AO-51 while the satellite is eclipsed. Most tracking programs indicate 
illuminated or eclipsed states, and it can always be found by whether 
the footprint of the satellite is crossing or in contact with the 
footprint of the sun. Generally this is occurring when the satellite is 
south of 30 degrees latitude at present.

I realize this is a large favor to ask, but the alternative right now is 
moving to a scheduled type operation, which I would like to avoid. 
Please pass this to your friends, other users you know, and your 
national satellite email lists and forums.

Thank you and 73,
Drew KO4MA
