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.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 081 Issued at 2200Z on 22 Mar 2010IA. Analysis of Solar Active Regions and Activity from 21-2100Z to 22-2100Z Solar activity has been at very low levels for the past
24 hours. Region 1056 (N19W21) was in a gradual decay phase with
decreased spot count and area. No new regions were numbered today.
IB. Solar Activity Forecast
Solar activity is expected to remain
at very low levels for the next three days (23-25 March).
IIA. Geophysical Activity Summary 21-2100Z to 22-2100Z
The geomagnetic field has been at quiet levels for the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to remain at quiet levels for the next two days (23-24
March). Geomagnetic activity is expected to be at quiet to unsettled
levels on day three (25 March) due to the arrival of a weak coronal
hole high-speed stream.
