Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 98 Issued at 2200Z on 08 Apr 2015
***** CORRECTION *****
IA. Analysis of Solar Active Regions and Activity from 07/2100Z to
08/2100Z: Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was an M1 event observed at
08/1443Z from Region 2320 (S12E02). There are currently 2 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be low with a
slight chance for an M-class flare on days one, two, and three (09 Apr,
10 Apr, 11 Apr).
IIA. Geophysical Activity Summary 07/2100Z to 08/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 395 km/s at
07/2137Z. Total IMF reached 5 nT at 08/0649Z. The maximum southward
component of Bz reached -2 nT at 07/2225Z. Electrons greater than 2 MeV
at geosynchronous orbit reached a peak level of 450 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to minor storm levels on days one and two (09 Apr, 10
Apr) and quiet levels on day three (11 Apr).
III. Event probabilities 09 Apr-11 Apr
