Finish obsid 5610, an ACIS-S observation of the high redshift quasar SDSS J0002+2550; then obsid 5592, an ACIS-I observation of the supernova remnant RCW 103, to study variability of the central compact object; then into perigee passage.

EPH temp 89.48 degF NOTES/ISSUES/PROBLEMS From the 9am status meeting: 10 supports over the weekend. No issues. Three load segments uplinked, on-board loads good until 027:08:24. CAP 953 was run Saturday at 022:22:47 to take a 20 ks ACIS CTI run prior to resuming the astronomical observing program. Built and approved load JAN2305B to resume observing program. However, this load has a known problem with the day 028 HRC antico shield PMT HV turn on being too early relative the radzone exit. Since this is later in the week, and with the time pressure and impending snow storm on Saturday, the load was approved with the knowledge that an intercept load must be built and uplinked to replace the remainder of JAN2305B following the three segments which are already uplinked. These products are expected out today for review, with products for the JAN3105 week to follow tomorrow, or after the intercept load is approved. Eclipse Saturday was nominal. Last eclipse of the season will be tomorrow, at ~06:00 Sun is quiet. Low probability of CME or significant flaring. Activity should be low for the next 3 days. Science observing resumed at 023:06:30. A net 363 ks of scheduled science observing time was lost to the radiation shutdown. OCC is in progress installing AGASC1.6. SAUSAGE is using 1.6, but FOT/MP has no issues with scheduling against 1.5 and selecting stars with 1.6. Various meetings postponed one day due to the snow storm. Smithsonian is officially closed today. Thanks to the people who stayed at the OCC through the storm over the weekend and worked up to 24 hr shifts! Quick look data: OBSID Target Time Comment ----- ------ -------------- ------- No new images due to radiation shutdown. ------------------------------------------------------- Dan Schwartz, MS #3 das@head-cfa.harvard.edu phone: (617)495-7232 FAX: (617)495-7356 cell phone: (617)512-5627 pager: 877-693-7198 PIN 693-7198 or e-mail 6937198@archwireless.net -------------------------------------------------------
