(Times will be given in GMT on day 258. In general
times are rough, not precise.)

PLAN
Continue 200 Ksec observation of HR1099 using ACIS-S/HETG, 
  coordinated with HST.

EVENTS
Start shift out of comm.  Format 2, OBSID 62538, pointed at 
  RA=54.21575, dec = 0.57374, roll= 100.27239. HETG IN, at
  ACIS-S aim/focus position. (This is from note 7 of previous 
  shift report, M54)


NOTES/ISSUES/PROBLEMS
Have planned for possible ACIS activities tomorrow. The concern is
the potential for conflict with the eclipse operations. However, 
from a power standpoint the potential activities only involve
4 watts of focal plane heaters. So ACIS is cleared to either do,
or not do, activities involving the focal plane up to -60 deg C.
There are available line-of-sights for extended comm passes 
tomorrow -- pending discussions at Lincoln labs this am the ACIS
team may ask for some in order to do diagnostic activities 
on day 259.
