Detector issues

G8 is continuing to show a very slow decay in emerging from night +SAA passes. The HV was lowered by 5 counts on October 24 at about 21:09UT. The voltage now sits at 3455.9 V. It seems the detector is getting noisier.

There were a couple of spike in all detectors on 28-Oct-2012 at about 12:25, 17:30 and 17:40, lasting for just a couple of minutes.
