(Times: hhmm or ddd:hhmm, not precise.)

Plan: complete ACIS bakeout, cool ACIS back down, do event histograms and
faint mode data collection with ACIS. Also review next p load at 11 pm.

NOTES/ISSUES/PROBLEMS 
--------------------- 

2215 We approved CAP 426 to increase grating retraction cycle duration
from 6 to 9 minutes, to address the problem of power not being turned
off after retraction.

2245 We approved ACIS CAP, 429 for event histograms and faint mode
data collection after it is cooled back down to be executed at
257:0200, 257:0220.

0038 SIM move ended up at TSC=-99608.

0300	p14 review telecon: Wallace Jackson emphasized that there
should be no load changes from 24 hr before, or during eclipse. This means that
there should be no events like ACIS bakeout during that time. The
entire p14 load has essentially one long observation of HR1099, broken
into two obsids, 64 before eclipse, and 1252 after, with ACIS-S and
HETG. Several issues are outstanding as of end of this telecon,
including the need for a review with ACIS, so final review will take
place tomorrow AM.
