Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 46 Issued at 2200Z on 15 Feb 2016
IA. Analysis of Solar Active Regions and Activity from 14/2100Z to
15/2100Z: 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
15/1100Z from Region 2497 (N12W62). There are currently 3 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 (16 Feb, 17 Feb,
18 Feb).
IIA. Geophysical Activity Summary 14/2100Z to 15/2100Z: 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
449 km/s at 15/1848Z. Total IMF reached 8 nT at 15/0509Z. The maximum
southward component of Bz reached -6 nT at 15/2043Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 114 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (16 Feb), quiet to minor
storm levels on day two (17 Feb) and unsettled to active levels on day
three (18 Feb). Protons have a slight chance of crossing threshold on
days one, two, and three (16 Feb, 17 Feb, 18 Feb).
