At 185/10:35 the WFC CCD detector started and shortly thereafter
successfully completed its first exposure/readout using the side 2
electronics. The HRC CCD first exposure/readout using its side 2 electronic
occurred at 185/11:06 and was also successful. All temperature and voltages
continue to remain within family.

Also, The Payload FSW team has reported back initial result of the ACS MEB2
memory integrity. The PROM, EDAC, EEPROM and MIE all verified GOOD.
Results of the CS Buffer RAM will be available after a final two memory
dumps are collected.

The WFC TEC successfully cooled the WFC CCD detector down to its new
setpoint of -81.0 dgC. Ops Request 17807 was executed to set the ACS
NSSC1 event flag #8 after the STScI and GSFC engineers determined the
TEC was stable at this new temperature. Setting of event flag #8
prevents stored commanding at 185/16:30 form returning the WFC TEC to it
initial setpoint of -77.0 dgC.

The WFC housing temperature started at 5.37 dgC and is stable at 6.35
dgC right now. The TEC current at -77 was 2.16a and is presently
holding in the 2.5a vicinity.

The first external images scheduled for the WFC CCD detector begin at
186/01:40 (Tuesday 9:40pm) and the HRC CCD detector will begin its
external images at 186/14:10 (Wednesday 10:10am).
