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 177 Issued at 2200Z on 25 Jun 2012IA. Analysis of Solar Active Regions and Activity from 24-2100Z to 25-2100Z Solar activity increased to low. New Region 1512
(S16E39, Dao/beta) emerged early on 25 June and gradually grew
during the remainder of the period. It produced a C1/Sf flare at
25/2059Z. A long-duration B7 flare occurred at 25/1848Z from a
region beyond the southeast limb. No Earth-directed coronal mass
ejections were observed during the period.
IB. Solar Activity Forecast
Solar activity is expected to be very
low during the period (26 - 28 June) with a chance for a C-class
flare.
IIA. Geophysical Activity Summary 24-2100Z to 25-2100Z
The geomagnetic field was at quiet to unsettled levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet during the period (26 - 28 June) with a chance
for unsettled levels.
