Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 92 Issued at 2200Z on 02 Apr 2014
IA. Analysis of Solar Active Regions and Activity from 01/2100Z to
02/2100Z: Solar activity has been at high levels for the past 24 hours.
The largest solar event of the period was a M6 event observed at
02/1405Z from Region 2027 (N12E42). There are currently 7 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be low with
a chance for M-class flares on days one, two, and three (03 Apr, 04 Apr,
05 Apr).
IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
496 km/s at 02/0355Z. Total IMF reached 6 nT at 01/2331Z. The maximum
southward component of Bz reached -4 nT at 01/2149Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (03 Apr, 04 Apr) and quiet to
active levels on day three (05 Apr). Protons have a slight chance of
crossing threshold on days one, two, and three (03 Apr, 04 Apr, 05 Apr).
III. Event probabilities 03 Apr-05 Apr
Class M 40/40/40
Class X 05/05/05
