Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 234 Issued at 2200Z on 22 Aug 2015
IA. Analysis of Solar Active Regions and Activity from 21/2100Z to
22/2100Z: Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M2 event observed at
22/1323Z from Region 2403 (S14E09). There are currently 2 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be moderate
with a slight chance for an X-class flare on days one, two, and three
(23 Aug, 24 Aug, 25 Aug).
IIA. Geophysical Activity Summary 21/2100Z to 22/2100Z: 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
499 km/s at 21/2207Z. Total IMF reached 10 nT at 22/1130Z. The maximum
southward component of Bz reached -5 nT at 22/1217Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 6539 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at unsettled to minor storm levels on days one and two (23 Aug, 24
Aug) and quiet to active levels on day three (25 Aug). Protons greater
than 10 Mev have a slight chance of crossing threshold on day three (25
Aug).
