Solar activity report
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 188 Issued at 2200Z on 06 Jul 2012IA. 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.
