(Times will be given in GMT on day 260. In general
times are rough, not precise.)

PLAN
Finish running load P14b: do OBSID 1252 to finish HR1099 observation 
  using ACIS-S/HETG. P14b ends at 260:17:35:00
Load and activate P15.
Next comm:  260:18:25 to 261:00:50. 



EVENTS
Expect radiation exit at 260:10:56:07.620.
Start shift out of comm.  As stated in last report, H56, 
  status was exactly as expected at last LOS.

18:10  AOS, Start comm early. Start CAP 440



NOTES/ISSUES/PROBLEMS
P14b will expire around 260:17:35, so there will be a gap
  before p15 takes over.  Plan is to do the ACIS post-belt
  calibration via real time command when comm is established
  at 18:25, and have the P15 load take over roughly at ~20:30.
  Observing time on Abell 401 will be reduced by up to about 
  an hour, or about 10%. 

We met at 1pm today in the action room to review the real time
  operations prior to the beginning of P15 load. These are to 
  carry out the post-belt ACIS CTI measurements with their
  external radioactive source. This approves CAP 440 to 
  change to OBSID 62535 for the HRC-S position. Then we
  will upload the P15 load, return to ACIS-S position, then
  activate the P15 load after we confirm we are in the proper
  initial configuration.
