Solar Activity

This week the Sun was particularly active considering that we are entering into quiet zone period of the solar cycle. Starting last Wednesday, AR2567 hosted a total of six C-class flares. The peak of activity occurred on Thursday when this same active region 9 C-class flares and 2 GOES M-class. During the weekend five intense solar limb M-class flares and a total of 15 C-class flares were caused by the same AR. After that "party of solar flares," things began to quiet down this week with just a couple of small flares and a GOES background that fell to a constant B-class.

As a particular situation, the Solar NuSTAR team got solar observation time for yesterday, so during the weekend we prepared RHESSI to support those observations. We expect to hear soon from the NuSTAR team to tell us whether the found something interesting during their observations.

Memory Management

Decimation was normal/vigorous for the full time period. The SSR is empty. Detectors 3 and 8 are on full-time, including spacecrft night, and rear segment decimation is turned off.

Spacecraft Status

Detectors 3 and 8 are powered on, and are recording events. The cold plates, 1 and 2 are at 136.5 and 135.2 K. Detector 1 was turned off at 19:37 Ut on 4-july-2016. The cold tip temperatures are 114 and 112 K; the average value of the sum of cold tip temperatures for 7-july-2016 0:00 to 16:00 is 1113.03+-0.28 K. Prior to the turn off of D1, the cold tip temperature average was rising at a rate of approximately 0.2K per day. THe turn off appears to have arrested this increase.

Data Gaps

The many short data gaps are due to noisy data connections for Wallops files.

Detector issues

Detectors 3 and 8 are powered on, and are recording events. No excess large numbers of resets or fast or slow rates at present. All other detectors are off.
