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 02-2100Z to 03-2100Z

Solar activity remained at the low level. Very little eruptive activity occurred, but the disk did experience considerable change from yesterday. Six new regions were numbered. They are: 9250 (S11W80), 9251 (S22W34), 9252 (S02W36), 9253 (S14E11), 9254 (N10E59), and 9255 (N21E64). All are simple and small.
IB. Solar Activity Forecast
Solar activity is expected to persist at the low level.
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
The geomagnetic field was quiet to active. A prolonged period of southward IMF caused the weak disturbance during the latter half of the interval.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet to unsettled.
