News and Events -- May 22, 2013
The geomagnetic field was quiet on May 21. Solar wind speed at SOHO ranged between 346 and 536 km/s. A weak disturbance began after 16h UTC and has intensified early on May 22.
Solar flux measured at 20h UTC on 2.8 GHz was 125.3 (increasing 10.6 over the last solar rotation). The background x-ray flux was at the class B6 level.
At midnight UTC the visible solar disk had 11 spotted active regions (in 2K resolution SDO images):
Region 11745 [N14W67] decayed slowly and was mostly quiet.
Region 11746 [S28W63] decayed slowly and quietly.
Region 11748 [N14W29] lost the magnetic delta structure. While there is polarity intermixing, the region is decaying slowly.
Region 11753 [N05E47] lost penumbral area while gaining a few spots.
Region 11754 [S19E38] was quiet and stable.
New region 11755 [N10E67] rotated into view on May 20 and was numbered the next day by SWPC. The region has polarity intermixing and could produce C and minor M class flares.
New region 11756 [S20E53] emerged on May 20 and was numbered by SWPC the following day. The region began to produce C flares late in the day.
Spotted regions not numbered by SWPC:
S2431 [S20E18] gained a leading penumbra spot.
S2432 [S17E41] decayed slowly and quietly.
New region S2436 [N05E33] emerged with penumbra spots.
New region S2437 [N15E27] emerged with a penumbra spot.
