Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 261 Issued at 2200Z on 18 Sep 2015
IA. Analysis of Solar Active Regions and Activity from 17/2100Z to
18/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C6 event observed at
17/2115Z from Region 2415 (S20W16). There are currently 3 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 (19 Sep, 20 Sep,
21 Sep).
IIA. Geophysical Activity Summary 17/2100Z to 18/2100Z: 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
465 km/s at 18/1544Z. Total IMF reached 7 nT at 18/1209Z. The maximum
southward component of Bz reached -6 nT at 18/1149Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 3502 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (19 Sep), unsettled to minor
storm levels on day two (20 Sep) and active to minor storm levels on day
three (21 Sep).
