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 162 Issued at 2200Z on 10 Jun 2012IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z
Solar activity was moderate. Region 1504 (S18E51)
produced an M1 flare at 10/0645Z and grew to end the period as a Dac
type group with a beta magnetic configuration. New Regions 1506
(N11E66) and 1507 (S26E29) were numbered today and classified as Cao
and Dao type groups, respectively, with beta type magnetic
configurations. The remaining regions were generally stable.
IB. Solar Activity Forecast
Solar activity is expected to range
from low to moderate. An isolated M-class event is likely from
Region 1504.
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
The geomagnetic field was generally at quiet levels. Wind speed at
the ACE spacecraft was approximately 440 km/s through the period.
The Bz component of the interplanetary magnetic field ranged between
+/-4 nT. The greater than 2 MeV electron flux at geosynchronous
orbit was at high levels throughout the period.
IIB. Geophysical Activity Forecast
The geomagnetic field activity
is expected to range from quiet to unsettled levels for the next
three days (11-13 June) with a chance for an isolated active period
on the first two days. A weak coronal hole high speed stream is
expected on day one (11 June) and a glancing blow from the 08 June
CME is expected on day 2 (12 June). Day three will see a return to
mostly quiet conditions.
