Solar Activity

Solar activity began high with the gigantic AR 12192, but then tapered off as the region rotated over the limb. Activity has picked up in the past 48 hours as AR 12205 rotated on disk and produced a series of large M-class flares. This spot is expected to produce some additional large events in the coming days.


How many GOES flares occurred?

 Flares above B, C, M, X class were      3    34    14     0

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

 Flares above B, C, M, X class were      0    22    13     0

And how many had EXCELLENT coverage?

 Flares above B, C, M, X class were      0    11    5     0

There were RHESSI flares/GOES flares 324 / 51 over the time range 22-Oct-14 29-Oct-14


Memory Management

SSR emptied by mid-week and has been continuing to empty at the end of the pass sets. We remain in Active/Vigorous mode and night time time data collection remained off throughout the week.

Temperature

Spacecraft Operations

Attenuator motion was nominal.

Data Gaps

No data gaps this week.

Detector issues

Detector 2: Light leak issues persist

Detector 9: Over the time period of Oct 31 - Nov 2, D9's monitor rates plots show elevated noise. The onset was sudden, as was the end. There was a 45 minute period on Nov 1st, from 19:00 - 19:45, when the noise returned to normal values. Since Nov 2nd, D9 has had normal levels of noise. There are currently no theories as to why this occurred.

There were no threshold changes this week.

Night time data (rears) Full nighttime events stopped
Require extra passes? Yes
