On Sun, 7 Nov 2004 10:10:02 EST
a radiation violation of P3 (130Kev) was observed by ACE.
Observed = 3.7863e+08
(limit = fluence of 3.6e8 particles/cm2-ster-MeV within 2 hours)
SCS107 commanded manually at 312:19:54.
The load stoppage left Chandra at a warm EPHIN attitude. We saw a peak
temperature of 104 F and voltage drop to 11 V.
On Sun, 7 Nov 2004 20:37:01 EST
a radiation violation of the USAF Kp index occured.
Value = 7.33 (dynamic limit: 6.3)
On Tue, 9 Nov 2004 04:25:01
another radiation violation of P3 (130Kev) was observed by ACE.
Observed = 3.8035e+08
(limit = fluence of 3.6e8 particles/cm2-ster-MeV within 2 hours)
Loads were restarted at 2004:315:16:15 UT, but SCS107 tripped
autonomously at 2004:315:16:41 due to high radiation.
SCS107 ran during a scheduled manuever sequence when ACA-restart was disabled.
Due to the normal motions of SIM translation, guide stars were lost and Normal
Sun Mode was entered. Nominal recovery from NSM occurred at 2004:316:02:50 UT.
The radiation environment is subsiding and observations are expected
to resume at 2004:318:03:45 UT.
Estimated lost science time: 307 ks (11/07-11/13)
CTI page
was updated. 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.
The values quoted below are temperature factor corrected ones.
Average of ACIS-I CCDs (MnKa) slope 5.556e-9 CTI/day
Detrended slope 6.510e-9 CTI/day
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.

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