Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 266 Issued at 2200Z on 23 Sep 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
23/1857Z from Region 2422 (S20E36). There are currently 6 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 (24 Sep, 25 Sep,
26 Sep).
IIA. Geophysical Activity Summary 22/2100Z to 23/2100Z: 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
574 km/s at 23/0640Z. Total IMF reached 15 nT at 23/1359Z. The maximum
southward component of Bz reached -8 nT at 23/1559Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 531 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (24 Sep) and quiet to
active levels on days two and three (25 Sep, 26 Sep).
