Will re-schedule when go-ahead is received. Could have late load review today if change approval comes in soon. S/C Engineering(Dan/Eric/Mike): - Limit violations in propulsion system on Jan 1. Will investigate. - Had another occurrance of RFI on Dec 25 (like the one on Dec 5). In this case we got both carrier and command lock. Will pass along information to MSFC. SOT(Bill): - Radiation flux level (soft protons) is high (5000) but decreasing. ACIS is not in focal plane until 004:0038, so there is no accumulated fluence on ACIS at this point in time. Predicted fluence from time when ACIS goes into focal plane until radzone entry is below budget. - EPHIN P4GM channel was about 50 in pass vs. 300 limit. - We noted that the HRC shield rate was above 10,000 cts/sec during this morning's pass. This is a red limit condition on the HRC GSE. HRC personnel were contacted (A. Kenter, G. Austin) and they indicated to us that this rate would be normal under the current radiation conditions and is not a problem. DSOPS(Joy): - Several QL's, see below - One FID light lost on obsid 3144. GOT(Ken/Chris): - All is OK. - Chronicle TV program will be filming later on today.
