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 074 Issued at 2200Z on 15 Mar 2010IA. Analysis of Solar Active Regions and Activity from 14-2100Z to 15-2100Z Solar activity has been at very low levels for the past
24 hours. Region 1054 (N14W14) has showed slight decay but continues
to maintain its magnetic Beta-Gamma configuration. No new regions
were numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be at
very low to low levels for the next three days (16-18 March).
C-flares are likely from Region 1054. There is a slight chance for
an isolated M-class event also from this region.
IIA. Geophysical Activity Summary 14-2100Z to 15-2100Z
The geomagnetic field has been at quiet levels for the past 24 hours.
The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels during the period.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at quiet to unsettled levels for the next three days
(16-18 March). The increase in activity is due to a recurrent
coronal hole high-speed stream on day one and day two, and a slow
moving partial halo CME observed on 13 February arriving late on day
three.
