Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 192 Issued at 2200Z on 11 Jul 2017
IA. Analysis of Solar Active Regions and Activity from 10/2100Z to
11/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
11/2031Z from Region 2665 (S06W03). There are currently 1 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, two, and three (12 Jul, 13 Jul,
14 Jul).
IIA. Geophysical Activity Summary 10/2100Z to 11/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 640 km/s. Total IMF reached 10 nT at
10/2147Z. The maximum southward component of Bz reached -3 nT at
11/0303Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 477 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (12 Jul), quiet levels on
day two (13 Jul) and unsettled to active levels on day three (14 Jul).
