Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 43 Issued at 2200Z on 12 Feb 2016
IA. Analysis of Solar Active Regions and Activity from 11/2100Z to
12/2100Z: Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M1 event observed at
12/1047Z from Region 2497 (N13W19). There are currently 5 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 (13 Feb, 14 Feb,
15 Feb).
IIA. Geophysical Activity Summary 11/2100Z to 12/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
375 km/s at 12/0249Z. Total IMF reached 16 nT at 12/1938Z. The maximum
southward component of Bz reached -11 nT at 12/0752Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (13 Feb) and quiet to
minor storm levels on days two and three (14 Feb, 15 Feb). Protons have
a slight chance of crossing threshold on days one, two, and three (13
Feb, 14 Feb, 15 Feb).
III. Event probabilities 13 Feb-15 Feb
