NOTES/ISSUES/PROBLEMS
From the 9am status meeting:
     Three supports, no issues, one load segment uplinked, on-board 
loads good through 097:08:34.
      Load review of APR0703A gave some minor cleanups, APR0703B will 
be out this morning for an email-only review this afternoon.
      ASVT issues have prevented checkout of the products to swap 
to VDE-B side. These are believed resolved, and will attempt again
this afternoon. Gyro 1 current was observed to increase very rapidly 
from 122 to 128 ma yesterday.  The levels are well within what has 
been observed although the change is a little more rapid than 
previously. No cause for action. 
      Telecon at 1pm today to review Rino's plan for handling eclipses 
for the remainder of the mission. 405 244 5060 #1165, see file
/pool14/chandra/Eclipse_Handling_Plan.doc
	The 3rd string was returned to operations as of about 7:15pm
last night.

Seven more survey fields: F7, F53, SS23, SS15, SD40, SS10, F47:
There are no recognizable targets, but no obvious problems. Jen and 
Eric both note that there are many poor star fields for this series.
