Solar activity report

Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

IA. Analysis of Solar Active Regions and Activity from 01-2100Z to 02-2100Z

SOLAR ACTIVITY WAS LOW. A SINGLE C4/1F EVENT OCCURRED IN REGION 8376 (S27E41) AT 02/1358UT. THIS IS A NEW NUMBERED REGION DUE TO THE FACT THAT IT CREATED AN X-RAY AND OPTICAL FLARE, EVEN THOUGH IT DOES NOT CONTAIN ANY SPOTS. ANOTHER NEW REGION WAS NUMBERED 8377 (N22E75). REGION 8377 IS ROTATING ONTO THE EAST LIMB AND CONTAINS A SINGLE SPOT AT THIS TIME. REGION 8375 (N19E20) PRODUCED A SINGLE OPTICAL FLARE. THE REST OF THE REGIONS HAVE BEEN MOSTLY QUIET AND STABLE.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE VERY LOW TO LOW. ISOLATED C-CLASS FLARES MAY OCCUR FROM REGIONS 8375 AND 8376.
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
THE GEOMAGNETIC FIELD WAS QUIET. ENERGETIC ELECTRONS AT GEOSYNCHRONOUS ORBIT WERE AT HIGH LEVELS FOR MOST OF THE PERIOD AND THEN FALLING BELOW THRESHOLD LEVELS AT 02/2000UT.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS EXPECTED TO BE QUIET TO UNSETTLED.
