Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 292 Issued at 2200Z on 19 Oct 2015
IA. Analysis of Solar Active Regions and Activity from 18/2100Z to
19/2100Z: 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
19/1727Z from Region 2436 (N09E44). There are currently 5 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 (20 Oct, 21 Oct,
22 Oct).
IIA. Geophysical Activity Summary 18/2100Z to 19/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 479 km/s at
18/2126Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 332 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at mostly quiet levels on day one (20 Oct), quiet to active levels
on day two (21 Oct) and quiet to unsettled levels on day three (22 Oct).
