Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 272 Issued at 2200Z on 29 Sep 2015
IA. Analysis of Solar Active Regions and Activity from 28/2100Z to
29/2100Z: Solar activity has been at high levels for the past 24 hours.
The largest solar event of the period was a M2 event observed at
29/0516Z from Region 2422 (S18W42). There are currently 5 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be moderate
with a chance for X-class flares on days one, two, and three (30 Sep, 01
Oct, 02 Oct).
IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z: 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
385 km/s at 29/0412Z. Electrons greater than 2 MeV at geosynchronous
orbit reached a peak level of 254 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (30 Sep, 01 Oct)
and quiet to active levels on day three (02 Oct). Protons have a chance
of crossing threshold on days one, two, and three (30 Sep, 01 Oct, 02
Oct).
III. Event probabilities 30 Sep-02 Oct
