Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 202 Issued at 2200Z on 20 Jul 2016
IA. Analysis of Solar Active Regions and Activity from 19/2100Z to
20/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C4 event observed at
20/0317Z from Region 2567 (N05W37). There are currently 3 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be low with a
chance for M-class flares on days one and two (21 Jul, 22 Jul) and
likely to be low with a slight chance for an M-class flare on day three
(23 Jul).
IIA. Geophysical Activity Summary 19/2100Z to 20/2100Z: The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 633 km/s at 20/0721Z. Total IMF
reached 34 nT at 20/0100Z. The maximum southward component of Bz reached
-28 nT at 20/0022Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 3426 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on days one and two (21 Jul, 22 Jul) and
quiet to unsettled levels on day three (23 Jul).
