Report of Solar-Geophysical Activity
Issued: 2010 Mar 15 2200 UTC
Prepared jointly by the U.S. Dept. of Commerce, NOAA,
Space Weather Prediction Center and the U.S. Air Force.
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 074 Issued at 2200Z on 15 Mar 2010
IA. 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.
