HUBBLE SPACE TELESCOPE

DAILY REPORT        # 3357

PERIOD COVERED: DOY 126

Part 3 of 3

ACS 9649

ACS internal CTE monitor

The charge transfer efficiency {CTE} of the ACS CCD detectors will
decline as damage due to on-orbit radiation exposure accumulates.
This degradation will be closely monitored at regular intervals,
because it is likely to determine the useful lifetime of the CCDs.
All the data for this program is acquired using internal targets
{lamps} only, so all of the exposures should be taken during Earth
occultation time {but not during SAA passages}. This program emulates
the ACS pre-flight ground calibration and post-launch SMOV testing
{program 8948}, so that results from each epoch can be directly
compared. Extended Pixel Edge Response {EPER} and First Pixel
Response {FPR} data will be obtained over a range of signal levels
for both the Wide Field Channel {WFC}, and the High Resolution
Channel {HRC}. 

ACS 9674

CCD Daily Monitor

This program consists of basic tests to monitor, the read noise, the
development of hot pixels and test for any source of noise in ACS CCD
detectors. This programme will be executed once a day for the entire
lifetime of ACS. 

NICMOS 9702

NICMOS Parallel Thermal Background

NICMOS Camera 2 pure parallel exposures in the F222M and F237M
filters to establish the stability of the HST+NCS+Instrument thermal
emission. This data will be compared against the already available
Camera 3 measurements in F222M which show an increased thermal
background. 

STIS 9708

STIS Pure Parallel Imaging Program: Cycle 11

This is the default archival pure parallel program for STIS during
cycle 11. 

WFPC2 9709

POMS Test Proposal: WFII parallel archive proposal

This is the generic target version of the WFPC2 Archival Pure
Parallel program. The program will be used to take parallel images of
random areas of the sky, following the recommendations of the 2002
Parallels Working Group. 

WFPC2 9710

POMS Test Proposal: WFII backup parallel archive proposal

This is a POMS test proposal designed to simulate scientific plans.

FLIGHT OPERATIONS SUMMARY:

Significant Spacecraft Anomalies: (The following are preliminary
reports of potential non-nominal performance that will be
investigated.) None

SIGNIFICANT EVENTS:
In preparation for Battery 2 Capacity Test, successfully dumped 486
memory {at} 126/16:05Z to verify SMAC20, Version I and HMAC09 are loaded
in memory (OR 16974-1).  At complete of memory dump collection, built
Best Estimate file and notified FSW dump available for verification.
Battery 2 Capacity first opportunity 127/13:01Z (OR 16970-2).
