Radiation

On 15 Feb, region 1158 produced an X2.2 flare.

Date: Thu, 17 Feb 2011 16:00:00 -0500 (EST)
A Radiation violation of P3 (130keV) scaled from P6 (761keV) was observed by ACE

Date: Thu, 17 Feb 2011 21:37:47 -0500 (EST)
 A Radiation violation of P3 (130Kev) was observed by ACE
 Observed = 3.7969e+08
 (limit = fluence of 3.6e8 particles/cm2-ster-MeV within 2 hours)

Date: Thu, 17 Feb 2011 21:55:00 -0500 (EST)
ACIS ALERT!! ACE p+!
ACIS P3 fluence = 1.00e+09 p/(cm2-sr-MeV), in previous 42.4 hrs
Above limit=1.0E+09

No spacecraft safing action was needed because the rates quickly decreased.
Total orbital ACIS P3 fluence is about 1.120e+09 p/(cm2-sr-MeV).

Fast-growing active region 1161 erupted on Feb 18, producing an M6.6-class 
solar flare at 1011 UT. SOHO coronagraph images show no accompanying CME, 
so Earth effects should be minimal.

Although we have quoted CTI values of the cleanest data (FT <= -119.7 C, int time > 7000sec), the data fills these conditions are getting rare. We quote CTI temperature factor corrected ones. The values in the parentheses are CTI based on the cleanest data.

Average of ACIS-I CCDs (MnKa) slope:	1.759e-9 CTI/day	(1.259e-9 CTI/day)
Detrended slope:	7.368e-9 CTI/day	(7.211e-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 long peak is observed.

Day (DOY)	Temp (C)	Width (Days)
47.11	-117.49	2.15

Weekly focal plane temperature with sun angle, earth angle, and altitude overplotted. Sun angle is the solar array angle, that is the angle between the sun and the optical axis (+X axis). The earth angle is the angle between earth and the ACIS radiator (+Z axis). Altitude varies from 34 kkm to 128 kkm.

Min/max envelopes in dark blue appear on the trending plots. The envelopes are 4th degree fits to the monthly minimum and maximum values for each MSID. The final polynomial form and binning are still being experimented with. We will soon add to the trending pages a report of the fits and predictions they give on future limit violations. The light blue curve is our original smoothing of all the data over 30 day moving boxcars. The green/yellow line is a linear fit to all the data; the break occurs at a limit change.
