Fast growing sunspot 1199

New sunspot 1199 is growing rapidly in the sun's northern hemisphere, ballooning in area by more than a factor of five during the last 24 hours. If the expansion continues apace, this active region could soon pose a threat for flares. Stay tuned. (SpaceWeather)



New Sunspot 1199 which is located in the northern hemisphere is growing fairly quickly and may be capable of producing isolated C-Class flares. Continue to monitor this region for further development.

New sunspot 1200 and existing sunspot 1196 which are both located in the southern hemisphere are fading . Sunspot 1195 which continues to transit the southern hemisphere remains quiet. (SolarHam)



Two new regions were numbered today, Region 1199 (N21W23) and Region 1200 (S17E42). Region 1199 emerged quickly on the disk and is already classified as a C-type group. (Prepared jointly by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center and the U.S. Air Force.)
