The ARRL Solar Update  Kijk naar?

Solar activity was at very low levels with only isolated B-class
flaring, mostly from Region 4416.
 
There are currently four numbered regions on the visible disk. Region
4416 remains the largest group by area but exhibited signs of
structural weakening, including flux submergence and a slight decay
of its intermediary pores. Region 4419 was the most complex group on
the disk and showed flux emergen...

The ARRL Solar Update  Kijk naar?

Solar activity remained at low levels this week. Most of the C-class activity came from either Region 4414 or Region 4409, which has developed a delta spot in its intermediary area. All remaining spots were either stable or in slight decay, with Region 4406 rotating over the west limb by the end of the reporting period.
 
Coronal activity was observed in CCOR-1, LASCO and STEREO available imager...

ARRL Solar Update  Kijk naar?

Solar activity was at low levels with seven numbered active regions

on the disk.

 

The largest event of the period was a C3.7 flare on March 25 from

Region 4400. Region 4403, which was numbered last period, is the

suspected source of several flares observed beyond the limb prior to

its rotation onto the disk. Due to its proximity to the northeast

limb, foreshortening continues to prevent a definitive

The ARRL Solar Update  Kijk naar?

Solar activity was very low to low. Only low-level C-class activity
was observed from Regions 4384 and 4389. Slight growth was observed
in Regions 4384 and 4391. New Region 4392 was numbered. The rest of
the spot groups were either stable or in decay. No Earth-directed
CMEs were observed. Solar activity is expected to be at low levels,
with a slight chance for M-class (R1-R2/minor-moderate) flares,
