Radiation

The radiation level crept up from Jul 23. The solar flare activity was quite high on July 25, and a total of 5 C and 4 M class events were recorded. A large full halo CME was observed after a long duration M1 proton event. Because of these activities, SCS107 was run twice during this period. The first one was July. 26th 04:06:28, and the second one was 27th 03:50:32 (both in UT).

Detrended CTI

CTI page was updated this week. 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.

Average of ACIS-I CCDs (MnKa) slope 6.427e-9 CTI/day
Detrended slope 7.046e-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.


ACIS Focal Plane Temperature

For this period, 3 peaks are observed.

Recent Observations

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