Solar Activity

Solar activity this week was low to moderate. There are currently 10 ARs on disk, several of which have produced a number of low C class flares (C1-3) over the previous few days. The most active of those are ARs 12010 and 12014, both of which will remain on the disk for the first half of next week.

How many GOES flares occurred?

 Flares above B, C, M, X class were      0    51     2     0

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

 Flares above B, C, M, X class were      0    25     2     0

And how many had EXCELLENT coverage?

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

There were RHESSI flares/GOES flares 132 / 53 over the time range 19-Mar-14 26-Mar-14


Memory Management

The SSR reached a max of ~40%.

Spacecraft Status

Cold plate temperatures are 118.0K and 116.8K. Cryocooler is operating normally.

A spin up was carried out on the 2014/078 at 20:06 and 21:48 UTC.

Data Gaps

There were several data gaps on the 23rd and 24th of March 2014. The data now appears in the browser, however there appears to be a number of corrupted data packets.

Detector issues

Due to increased noise and leakage current on detector 3, the thin attenuator remained in after a flare at 07:00UT on the 22nd of March 2014. At 20:14 UT on the 25th of March the detectors used for the detector livetime calculation was changed from 1, 3, 4 and 7 to 1, 4, 5, and 7.

Detectors 6 and 8 showed increased counts in the fast LLD and decreased livetime similar to previous weeks.

On March 20th the G6 front fast valids were once again above 200k cps and the live time had dipped as low as 2%. The G6 HV was lowered by 10 steps. The G6 front fast valids came down to around 7500 cps and the live time increased to 83%.

14-080-00:41:44 /IHVDAC DETECTOR=6, VOLTAGE=148

On the 21st March 2014 the G6 front fast was raised from 0xB0 to 0xC0 and G8 Rear fast was raised from 0x80 to 0x90.
