Radiation

SCS107 was tripped by radiation from Solar M7 flare at 360:0630 (Dec 26). A nominal EPHIN trip, and instruments are correctly safed. E1300, P4GM, P41GM rates are now all above EPHIN threshold.

ACIS/Radiation Environment correlations

CTI Trend

Average of ACIS-I CCDs (MnKa) slope 1.243e-8 CTI/day
Detrended slope 1.189e-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.
