Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 171 Issued at 2200Z on 19 Jun 2012
IA. Analysis of Solar Active Regions and Activity from 18/2100Z
to 19/2100Z: Solar activity was low. Region 1504 (S16W65) produced
a C1 flare at 19/1335Z which was the largest event of the period.
New Region 1510 (S16E02) was numbered today and is a small bi-polar
group. There were no Earth-directed CMEs observed during the
period.
IB. Solar Activity Forecast: Solar activity is expected to be low
with a slight chance for an isolated M-class flare from Region 1504.
IIA. Geophysical Activity Summary 18/2100Z to 19/2100Z:
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit reached high levels during the period.
IIB. Geophysical Activity Forecast: Geomagnetic activity is
expected to be quiet on 20-22 June.
