Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 187 Issued at 2200Z on 05 Jul 2012
IA. Analysis of Solar Active Regions and Activity from 04/2100Z
to 05/2100Z: Solar activity was high. Region 1515 (S17W36) produced
an M6/1b at 05/1144Z along with several low-level M-class flares.
The region continued to grow slightly in areal coverage and
maintained a beta-gamma-delta magnetic configuration. Region 1513
(N15W52) grew as well but did not produce any further M-class
activity since yesterdays report.
IB. Solar Activity Forecast: Solar activity is expected to be
moderate with a chance for X-class flares for the next three days
(06-08 July).
IIA. Geophysical Activity Summary 04/2100Z to 05/2100Z:
The geomagnetic field was quiet to unsettled with an isolated active
period due to residual effects from a coronal hole high speed stream
(CH HSS). Solar wind speed decreased throughout the period to
approximately 475 km/s. The greater than 2 MeV electron flux at
geosynchronous orbit was at high levels throughout the period.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be mostly quiet on days one and two (06-07 July) as
effects from the CH HSS subside. Unsettled to active conditions are
likely on day three (08 July), with a chance for isolated minor
storm periods, due to effects from the CME associated with the M1/2n
flare observed at 04/1639Z from Region 1513.
