[amsat-bb] Revised schedule AO-51 Feb-March 2011

[Mark L. Hammond]

As suspected, we're changing the schedule (due to a lack of full sun and to support the school contacts previously arranged in Alaska).  

The current schedule is below.  We may need to adjust again; changes will be communicated at the AO-51 website and here.
