|List all reports|
Solar activity this week was moderate with 3 M class flares. There are currently 10 active regions on the Sun, 6 of these will rotate over the limb within the next 48 hours. However a major flare watch has been called this morning for NOAA 1618, which has produced a number of C and M class flares over the last 24 hours (the largest was an M3.5 at 11/21/15:30 UT) and is currently in the center of the disk. NOAA 1618 has developed rapidly increasing its sunspot count, sunspot area, and magnetic complexity. 1618 is currently a large E-type/beta-gamma sunspot group with a magnetic delta configuration located within its central portion. There is a slight chance of an X-class event as well if 1618 continues in strong growth phase. STEREO B shows one further active region which will rotate onto the disk in the next few days.
How many GOES flares occurred?
Flares above B, C, M, X class were 8 33 3 0
And how many of these are listed in the RHESSI flare list?
Flares above B, C, M, X class were 7 21 3 0
And how many had EXCELLENT coverage?
Flares above B, C, M, X class were 2 6 0 0
There were RHESSI flares/GOES flares 280 / 44 over the time range 14-Nov-12 21-Nov-12
The SSR is emptying by the end of the daily pass set (max was ~25% this week). The decimation state was changed from active/vigorous to normal/vigorous at 2012-320-18:27:43 UTC.
We will remain in normal/vigorous for the time being, with the tohban keeping an eye on the SSR level in light of the major flare watch.
The cold plate 1 and 2 temperatures are 110.9 K and 108.6 K respectively.
There were a number of 5 min data gaps throughout the week.
There were no changes to the detector settings this week. However detector 5 front slow monitor rates are slightly higher than in previous weeks.
