Radiation

On Wed, 22 Oct 2003 05:37:02 (EDT) A Radiation violation of the USAF Kp index occured. Value = 5.67 (dynamic limit: 5.5)

On Fri, 24 Oct 2003 07:55:02 (EDT) A Radiation violation of P3 (130Kev) was observed by ACE Observed = 3.6708e+08 (limit = fluence of 3.6e8 particles/cm2-ster-MeV within 2 hours)

From Dan Schwartz, telecon report: This would exceed ACIS fluence budget, even for the interval from next ACIS observation to the next following COMM opportunity. Furthermore, a shock wave and at least one more CME is on the way, so we can anticipate an extended period of high rates, perhaps even for 2 more days

As a result the loads were terminated by ground command at ~ 297:13:34 GMT. Replan options are in progress.

Detrended CTI

Average of ACIS-I CCDs (MnKa) slope 8.525e-9 CTI/day
Detrended slope 8.646e-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, 1 large peak and several small peaks are observed.

SIM Movements

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.
