Detector 8 began to show an increased count rate coming out of the SAA, taking longer to decay than for the other detectors. The effect is particularly noticeable in the front slow and livetime monitor rates. The detector 8 HV was lowered by 5 steps at 2012-142-15:59:51 UT, bringing the HV down to 3921.6 V.
There were no data gaps this week.
