Solar Activity

Solar activity was higher than previous weeks with many C-class flares and 3 M-class flares. There are currently 7 ARs on the disk and 3 of them are expected to rotate off the disk within the next day or so. More C-class flares and isolated M-class flares are expected during the next few days.

How many GOES flares occurred?

 Flares above B, C, M, X class were      0    70     3     0

And how many of these are listed in the RHESSI flare list?

 Flares above B, C, M, X class were      0    54     3     0

And how many had EXCELLENT coverage?

 Flares above B, C, M, X class were      0    22     0     0

There were RHESSI flares/GOES flares 409 / 73 over the time range 10-Jun-15 17-Jun-15

Memory Management

The SSR fill level reached a maximum of ~50% and a minimum of about ~26% during the week.

Spacecraft Status

The cold plate 1 and 2 are at about 127.2 K and 125.7 K respectively.

Data Gaps

There were data gaps (as well as noisy data) due to the replays of data.

GAPS IN APP_ID = 102 (VC3-MONITOR RATES) WITH PACKET RATE LT 30

Other notes

Switched from normal_vigorous to active_vigorous at 2015-166-20:27:12 UTC (Jun 15, Monday). There has been stale TLE for about 4 days, leading to unstable tracking and many replays of data. It was considered that a change to "active_vigorous" would be a quick way to slow down the SSR filling up and allow us more time to replay the data.

There was a discussion on optimizing the threshold for shutter motions.
