Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 180 Issued at 2200Z on 28 Jun 2012
IA. Analysis of Solar Active Regions and Activity from 27/2100Z
to 28/2100Z: Solar activity increased to moderate levels. Region
1513 (N17E45) produced an impulsive M2/1b flare at 28/1612Z along
with occasional B- and C-class flares including a long-duration
C2/Sf at 28/1948Z. Region 1513 showed a minor increase in spot count
and an increase in magnetic complexity (beta-gamma). Region 1512
(S15W02) maintained its beta-gamma magnetic configuration, but
showed little change during the period. This region produced
occasional B- and C-class flares during the period. No new regions
were numbered. No Earth-directed coronal mass ejections occurred
during the period.
IB. Solar Activity Forecast: Solar activity is expected to be low
during the period (29 June - 01 July) with a chance for another
M-class flare.
IIA. Geophysical Activity Summary 27/2100Z to 28/2100Z:
Geomagnetic field activity was at quiet to (briefly) unsettled
levels.
IIB. Geophysical Activity Forecast: Geomagnetic field activity is
expected to be at quiet to unsettled levels on day 1 (29 June) with
a chance for active levels due to the arrival of a co-rotating
interaction region in advance of a recurrent coronal hole high-speed
stream (CH HSS). Field activity is expected to increase to unsettled
to active levels during days 2 - 3 (30 June - 01 July) with a chance
for minor storm levels due to CH HSS effects.
