Radiation

No alerts were issued this period, but M9 class flare was observed.
Lost Science time due to last week's interupt at was 93.5 ks (this includes 37ks of ObsId 4175).

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 8.201e-9 CTI/day
Detrended slope 8.461e-9 CTI/day

ACIS Warm Pixels



ACIS Focal Plane Temperature

For this period, 2 peak is observed.

SIM Movements

12 TSC moves this period
weekly average time/step 0.00135 s
mission average time/step 0.00136 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.
