On Dec 6, 0530 GMT there was an unexpected EPHIN 27V rail voltage drop. The observed temperature was 102.4 degF vs. predicted 96 (but the new model predicted 99.2). EPHIN 27V rail voltage had not recovered fully as of Dec 8. No alert page was sent out, which is being investigated by MTA.

MUPS 2A valve thermistor dropout were observed again Dec 7 and 8.

Quiet

Detrended CTI

CTI page was updated. The top panel shows an example of detrended CTI measurements from the front illuminated CCD3 Node 0. The top plot is all data points without any temperature dependency correction. The middle plot is data with the focal temperature equal or colder than -119.7 C, and the integration time longer than 7,000 sec. The bottom plot is all data with the temperature correction.

The values quoted below are temperature factor corrected ones.
Average of ACIS-I CCDs (MnKa) slope 4.189e-9 CTI/day
Detrended slope 7.599e-9 CTI/day

ACIS Warm Pixels

We display all bad pixels showed up in past, and, if any, previously unknown bad pixels appeared in the last 14 days. We also list hot pixels (defined as 1000 above the average of bias background). Warm columns 509-514 are probably due to a computational artificial effect due to boundaries.
