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 151 Issued at 2200Z on 30 May 2012IA. Analysis of Solar Active Regions and Activity from 29-2100Z to 30-2100Z Solar activity was low during the past 24 hours. A C1
x-ray event was observed at 30/0850Z from a region around the east
limb. All spot groups on the disk remained relatively quiet and
stable. No Earth-directed CMEs were observed during the period.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low with C-class activity likely for the next three days (31
May - 02 June).
IIA. Geophysical Activity Summary 29-2100Z to 30-2100Z
The geomagnetic field was quiet for the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mostly quiet for the next three days (31 May - 02
June).
