Radiation

Active sunspot 1261 unleashed several M-class flares, including an M9.3 at 0357 UT on August 4th.
Consequently, SCS107 was triggered autonomously by the HRC anti-coincidence counts at 2011:216:07:03:34z.

At 2011:216:22:25z a Radiation violation of P3 (130keV) scaled from P6 (761keV) was observed by ACE
Observed = 1.2129e+08
(limit = fluence of 1.2e8 particles/cm2-ster-MeV within 2 hours)

Detrended CTI

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: 2.062e-9 CTI/day (1.274e-9 CTI/day)
Detrended slope: 7.105e-9 CTI/day (7.139e-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, 3 peaks are observed.

Weekly focal plane temperature with sun angle and altitude overplotted. Sun angle is the solar array angle, that is the angle between the sun and the optical axis (+X axis). Altitude varies from about 5 kkm to 145 kkm.

Trending

This week's focus is EPHIN.

Last reported on May 12.

Only the most interesting or representative msids are shown below. For a full listing choose the bulletted link.

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.
