Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 195 Issued at 2200Z on 14 Jul 2010
IA. Analysis of Solar Active Regions and Activity from 13/2100Z
to 14/2100Z: Solar activity was low. Region 1087 (N20E08) produced
two C-class events. The first was a C1 flare at 14/1230Z and the
second was a C3 flare at 14/2047Z. 1087 is a Dso group with a
beta-gamma magnetic configuration and has shown little change in
areal coverage and spot number during the last 24 hours.
IB. Solar Activity Forecast: Solar activity is expected to be very
low to low. There is a slight chance for an isolated M-class event
from Region 1087.
IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z:
The geomagnetic field was mostly quiet. The solar wind monitor on
the ACE spacecraft indicated a sector boundary crossing into a
positive sector at approximately 14/0900Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be unsettled with a chance for isolated active periods
on day one (15 July) due to a coronal hole high speed stream. Quiet
conditions are expected to return on days two and three (16-17
July).
