A handful of other GOES B-class flares took place during last week. The AR responsible for most of the activity of past week is disappearing over the West limb, solar activity has moderately decreased in the past few hours, and is currently below B-level. Solarham shows a 10% of probability of having an M-class flare.

No overlapping RHESSI flares to count, sorry

Solar Activity

Very quiet week. A few B-class flares.


How many GOES flares occurred?

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

RHESSI flare list contains 0 over the time range 13-Feb-18 20-Feb-18

No overlapping RHESSI flares to count, sorry

Memory Management

At the beginning of this week we deleted data of February the 5th (by moving the read pointer):

2018-039-19:57:21 start sc_ssr_pnt (227359593)

The SSR is reaching a maximum of ~70% (!) and a minimum of ~65% at the end of a day. Next Tohban needs to consider to move the pointer again or deal with the detector noise to manage the SSR filling.

Spacecraft Status

Detectors 3, 6 and 8 are active and taking data.

The cold plate 1 and 2 temperatures are 158.863 K and 191.365 K.

Currently, the Cryocooler power is ~64.770 W and the acceleration is at ~13.354mg

Data Gaps

No apparent data gaps so far, but with the SSR full, we are lagging far behind.

= Detector issues

Other notes

A spin up was requested early today. No Attenuator motion this week. The attenuator threshold was set to XXX last Wednesday. The following operations were done that day:
