Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 160 Issued at 2200Z on 08 Jun 2012
IA.  Analysis of Solar Active Regions and Activity from  07/2100Z
to 08/2100Z:  Solar activity was low.  Region 1494 (S18W33) produced
a C7 flare at 08/0307Z.  The flare was accompanied by Type II and
Type IV radio emissions at 08/0305Z and 08/0308Z, respectively.  A
CME was observed in LASCO C2 imagery at 08/0443Z emerging from the
southern hemisphere.  Analysis of LASCO and STEREO COR2 coronagraph
imagery indicated a speed of approximately 380 km/s.  A subsequent
model run suggested a glancing blow at earth late on June 12th. 
Filament eruptions were observed from the NE limb at 08/1645Z in SDO
304 imagery and at 08/1756Z in LASCO C2.  A second eruption near
N10E50 was observed in SDO 304 imagery at 08/1706Z.  The first
eruption is not expected to be geoeffective; the second is being
evaluted.
IB.  Solar Activity Forecast:  Solar activity is expected to be low
with a chance for an isolated M-class event for the next three days
(09-11 June).
IIA.  Geophysical Activity Summary 07/2100Z to 08/2100Z:
The geomagnetic field ranged from quiet to unsettled levels.  Data
from the ACE spacecraft suggested the possible arrival of the CME
from 05 June around 08/0800Z.  A couple of unsettled periods
followed, but most of the day was quiet.  Wind speed at ACE declined
throughout the period and ended the day near 500 km/s.  The Bz
component of the IMF was generally neutral to slightly negative for
the first half of the day, and generally positive for the last half.
The greater than 2 MeV electron flux at geosynchronous orbit was at
high levels throughout the period.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet levels on day 1 (09 June).  The CME from 06
June is expected to arrive on day 2 (10 June), bringing unsettled
conditions with a chance for an isolated active period through day 3
(11 June).
