Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 186 Issued at 2200Z on 05 Jul 2014
IA. Analysis of Solar Active Regions and Activity from 04/2100Z to
05/2100Z: 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
05/0554Z from Region 2108 (S08E16). There are currently 10 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be moderate
with a slight chance for an X-class flare on days one, two, and three
(06 Jul, 07 Jul, 08 Jul).
IIA. Geophysical Activity Summary 04/2100Z to 05/2100Z: 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 325 km/s at
05/2104Z. Total IMF reached 5 nT at 05/1802Z. The maximum southward
component of Bz reached -5 nT at 05/1802Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (06 Jul, 07 Jul, 08
Jul).
