Radiation

Relatively quiet.
An Acis Fluence Alert was issued at 2001:348:00:15:01 UT
    Fluence limit of 1.00e+09 p/(cm^2-sr-MeV) exceeded.
    No action taken, fluence within budget for orbit.
Several M and X class flares 12/12-12/13, so stay tuned.

ACIS/Radiation Environment correlations

CTI Trend

Average of ACIS-I CCDs (MnKa) slope 1.293e-8 CTI/day
Detrended slope 1.226e-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.

ACIS Focal Temperature

For this period, no peaks were observed. Focal plane stayed cold the entire orbit.
