ACIS Shift report M1562 Nov 1 2003 00:04, GMT 305:05:04

ACIS Personnel:
Royce Buehler and Nancy Wolk, Paul Plucinsky participating by phone.

PLAN:

The sun having broken out with a terrible case of acne all week, we
finally got a chance to resume science. The ACIS team was particularly
eager to get some solid CTI data after an X18 and X11 flare exhibiting
a hard spectrum.

The intent was for OC to run CAP 617, enabling Radmon and SCS107;
then uplink the NOV0103 load ("Plan B"). Then ACIS would initiate
an ACIS-I CTI via CAP 892, which would run until the ACIS stop science
command in the load at 2003:305:14:15. This should give us about
35 ks of CTI data.

SUMMARY:

Radiation in the EPHIN E1300 channel being high, but consistently
below 1/3 of the trigger level, and all other radiation indications
being benign, we decided to proceed. The COM was smooth, and the 
plan executed without surprises or problems.
