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 214 Issued at 2200Z on 01 Aug 2012IA. Analysis of Solar Active Regions and Activity from 31-2100Z to 01-2100Z Solar activity was low. Regions 1528 (N17W56), 1532
(S19W14), 1535 (N18E37), 1536 (S22W01), and 1538 (S22E54) all
produced low level C-class flares. Region 1536 is the most
magnetically complex group on the visible disk with a weak
Beta-gamma configuration. No Earth-directed coronal mass ejections
(CMEs) were observed during the reporting period.
IB. Solar Activity Forecast
Solar activity is expected to continue
at low levels with a chance for M-class flares.
IIA. Geophysical Activity Summary 31-2100Z to 01-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled with isolated active periods
possible on day 1 (02 August) due to effects from the 28 July CME.
Quiet to unsettled conditions are expected on day 2 (03 August).
Mostly quiet conditions are expected on day 3 (04 August).
