Radiation

Quiet this week.
The ACE 47-65 KeV channel is suffering an anomaly. At this point our alerts are not impacted.

CTI Trend

Average of ACIS-I CCDs (MnKa) slope 1.198e-8 CTI/day
Detrended slope 1.126e-8 CTI/day

ACIS Warm Pixels

The following pixels consistently showed a bias level more than 5 sigma away the chip's mean level during this period.
We suspect some of the recurring bad pixels may be due to biases which are taken just after perigee, when the focal plane is somewhat warm. For more information see the link above and MTA monthly reports.

Due to a recent problem, all bad pixels are listed as "previously reported" for this week.
