Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 178 Issued at 2200Z on 27 Jun 2011
IA.  Analysis of Solar Active Regions and Activity from  26/2100Z
to 27/2100Z:  Solar activity remained at very low levels. Region 1236
(N16, L=170) produced two B-class flares from behind the west limb.
The most significant flare from Region 1236 was a long-duration B6
flare at 27/1542Z. Region 1241 (N18W46) produced a B3/Sf flare at
27/1216Z.
IB.  Solar Activity Forecast:  Solar activity is expected to be at
very low levels during the period (28 - 30 June), with a chance for
an isolated C-class flare.
IIA.  Geophysical Activity Summary 26/2100Z to 27/2100Z:
The geomagnetic field was at quiet levels, with isolated unsettled to
active levels at high latitudes. The greater than 2 MeV electron
flux at geosynchronous orbit reached high levels during the period.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet levels during the period (28 - 30 June).
