Report of Solar Geophysical Activity

 

Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 165 Issued at 2200Z on 13 Jun 2016

IA.  Analysis of Solar Active Regions and Activity from 12/2100Z to
13/2100Z: 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
13/0552Z from Region 2552 (N14, L=002). There are currently 2 numbered
sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be very low
with a chance for a C-class flares on days one, two, and three (14 Jun,
15 Jun, 16 Jun).

IIA.  Geophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 624 km/s at 13/0532Z. Total IMF reached 12
nT at 12/2225Z. The maximum southward component of Bz reached -8 nT at
12/2208Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 313 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (14 Jun) and quiet to active levels on
days two and three (15 Jun, 16 Jun).
