GOT installation of ONLS 3.9.3 has caused an interruption in the data capture sent to CXC. Realtime data is not affected, but dump data has not been received. Therefore, this report covers only the period 06/20/03 - 06/24/03. As of 1100 EDT on 06/27/03, dump data delivery has resumed.

Radiation

An autonomous SCS107 activation occurred at 173:18:48:41UT (2 hours before scheduled RADMON disable). This event is thought to be due to a 'puffed-up' belt state caused by high levels of coronal stream activity. Loads resumed at 174:12:00:00.
Obsids affected: 3871
Lost science time: 7.5 ks

Detrended CTI

CTI analysis is now computed with "detrending":
Detrend CTI = Measured CTI + S3 amplitude reject rate * Detrend factor.

Average of ACIS-I CCDs (MnKa) slope 8.152e-9 CTI/day
Detrended slope 8.399e-9 CTI/day

ACIS Warm Pixels



ACIS Focal Plane Temperature

For this period, 2 peaks are observed.

SIM Movements

9 TSC moves this period
weekly average time/step 0.00142 s

Telemetry

IRUs

The gyro bias level has remained unaffected by the change in current and so to date, there has been no impact to science or operations.


Recent Observations

"Prob" means that there was probably bad time data included in the manual runs. This will be corrected in future processing.
