| During the last week the observing schedule was replanned to include
an observation of SGR 1806-20 that was approved as a fast 3-day
turn-around Target Of Opportunity (TOO) on 25 May. Loads were
replanned and uplinked on May 26 for observing May 27. Observations of
RCrADarkCloud, LBQS 0010-0012 and CL0853+5759 were impacted by the TOO
and will be rescheduled for a later load.
A real-time procedure was completed on 24 May as part of a diagnosis of a stuck-on heater located on the Optical Bench Assembly (OBA) in Zone 50. The procedure turned off power to a set of survival heaters, including the one in Zone 50. After seeing no thermal response, the power was turned back on. The results indicated that the survival heater is functioning as expected (i.e. it is not stuck on). Additional work will proceed to trace the fault to the primary or redundant operational heater. The schedule of targets for the next week is shown below and includes 2 observations of the Moon. |
