Plan: Execute CAPs 394 for fid search box shrink, 396-8 for ACIS
anomaly diagnostics, while continuing with p12d load. Comm break
between 1900-2300 deleted.

NOTES/ISSUES/PROBLEMS 
--------------------- 
Rob reports no problems with ACA with Earth as close as 8 degrees.

Problem with ground system causes delay in AOS from 1745 to 1921.

Much delay in executing CAP 396 due to additional DSN problems. We got
thru step 4 of CAP 396, then had a long outage, resumed step 4b at
2107.

We did not go back to fmt1, nor do obsid 62412, because 1244 ran so
long.

ACIS diagnostic run, CAP 396, obsid 62413 shows a charge transfer
problem in front illuminated chip. 

We continued with CAP 398, Timed Exposure of Chips S2, S3, to further
explore the ACIS anomaly, using obsids 62411 & 62410.

Then we did CAP 397, Run all 10 Video Boards; Warm Boot; Do a DEA
Housekeeping Run; Leave ACIS in S-array EVT-histogram.
