Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 82 Issued at 2200Z on 23 Mar 2015
IA. Analysis of Solar Active Regions and Activity from 22/2100Z to
23/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C3 event observed at
23/0911Z. There are currently 8 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 (24 Mar,
25 Mar, 26 Mar).
IIA. Geophysical Activity Summary 22/2100Z to 23/2100Z: The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed, as measured by the ACE spacecraft, reached a peak
speed of 698 km/s at 23/0915Z. Total IMF reached 9 nT at 23/0434Z. The
maximum southward component of Bz reached -8 nT at 23/0311Z. Electrons
greater than 2 MeV at geosynchronous orbit reached a peak level of 7572
pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at unsettled to minor storm levels on day one (24 Mar), unsettled
to active levels on day two (25 Mar) and quiet levels on day three (26
Mar).
