Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 188 Issued at 2200Z on 06 Jul 2012
IA. Analysis of Solar Active Regions and Activity from 05/2100Z
to 06/2100Z: Solar activity was moderate. Region 1515 (S18W50)
continued to produce M-class flares, the largest an M2/Sn at
06/0140Z. The region continued to grow to 900 millionths and
maintained a beta-gamma-delta magnetic configuration. Region 1513
(N15W65) showed slight decay and is now considered an Hsx-alpha type
spot group.
IB. Solar Activity Forecast: Solar activity is expected to be
moderate with a chance for X-class flares for the next three days
(07-09 July).
IIA. Geophysical Activity Summary 05/2100Z to 06/2100Z:
The geomagnetic field was quiet to unsettled during the past 24
hours. The greater than 2 MeV electron flux at geosynchronous orbit
reached high levels during the period.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be unsettled to active with a chance for minor storm
conditions on days one and two (07-08 July) due to combined effects
from the CMEs observed on 03 and 04 July. Quiet to unsettled
conditions are expected on day three (09 July) as effects from the
CMEs subside.
