Solar Activity

After a quiescent during the last couple of weeks, the Sun was very active produced a string C-flares this week!!

How many GOES flares occurred?

 Flares above B, C, M, X class were     51     5     0     0

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

 Flares above B, C, M, X class were      7     2     0     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 13 / 56 over the time range 06-Feb-18 13-Feb-18

1) C8.1 around 20180207T1347. Really good coverage of the impulsive phase by RHESSI.
2) C4.6 around 20180210T1321. Missed all of the impulsive phase due to night time.
3) C1.5 around 20180212T0135. RHESSI has good coverage of the impulsive phase.

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.

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:

2018-038-20:26:16:  start sc_ats_load("T18039SLTN34.00")
2018-038-20:28:16:  start attenuator013_bg
