Sunspots Get Numbered



    We talked about yesterday the new numerous Sunpots on the disc get numbered .
Regions 1399 and 1400 emerged onto the solar disc. Regions 1401 and 1402 rotated over the north-east limb. As we all know this are the ones which produced the latest bigger Flares.
Region 1401 yesterday: C4.1 at 12:09, M1.4 at 13:18, C2.8 at 18:40, C2.1 at 21:54, C1.1 at 23:25 UTC. 1401 seems to be the more active one. 1402 above is the bigger one in size. All other groups shows up some changing in size and structure.
Region 1395 decayed slowly and was quiet. Region 1396 became less complex during the day although there is still weak olarity intermixing (flared yesterday morning C 2.1 03:35 UTC). Region 1397 decayed slowly and was quiet. Region 1398 lost penumbral area and gained a few spots. Region 1399 rotated into view at the southeast limb on January 13 and got an SWPC number the next day. This region flared before it rotated on the disc(noticed that on stereo). Region 1400 emerged in the southeast quadrant on January 13 and was assigned an SWPC number the next day.


     We expect C-flaring conditions for the coming 24 hours and an
increase in flaring activity due to the rotating on the disk of active
regions  1401 and 1402. Geomagnetic conditions remain quiet, with
a possibility of minor disturbances due to the high speed wind stream
from a narrow coronal hole.




spaceweather.com reports:
"These sunspots have the potential for strong eruptions. Sunspot 1401 produced an M1-flare on Jan. 14th. Two days earlier, while it was still on the farside of the sun, sunspot 1402 produced a partially-eclipsed flare of uncertain magnitude that created waves of ionization in the atmosphere over Europe"

New region 11401 [N17E76] rotated partly into view at the northeast limb. Flares: C4.1 at 12:09, M1.4 at 13:18, C2.8 at 18:40, C2.1 at 21:54, C1.1 at 23:25 UTC.
New region 11402 [N28E78] rotated partly into view at the northeast limb.
Spotted regions not reported (or interpreted differently) by NOAA/SWPC:[S1430] emerged in the southeast quadrant on January 14. Location at midnight: S18E42

NOAA forecasters estimate a 30% chance of more M-flares during the next 24 hours.
