Geophysical 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 Solar and Geophysical Activity Summary
SGAS Number 159 Issued at 0245Z on 08 Jun 2011 This report is compiled from data received at SWO on 07 JunA. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 0616 0641 0659 1226 S21W54 M2.5 2n 6400 710 II/IV
B. Proton Events
10 MeV and 100 MeV proton events are in progress.
The greater than 10 MeV proton flux began at 07/0820Z and reached a
peak flux of 72.9 pfu at 07/1820Z. The greater than 100 MeV proton
flux began at 07/0720Z and reached a peak of 4.5 pfu at 07/1025Z.
Both of these events are associated with the M2/2N flare at 07/0641Z
from Region 1226 and are currently declining.
C. Geomagnetic Activity Summary
The geomagnetic field ranged from
quiet to active levels.
