Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 120 Issued at 2200Z on 30 Apr 2010
IA.  Analysis of Solar Active Regions and Activity from  29/2100Z
to 30/2100Z:  Solar activity was low.  Region 1064 (N15E28) was
numbered today and produced a B1 flare at 30/0021Z.  The GOES-14
imagery observed a C2 x-ray flare at 30/1934Z.  The source of this
event was located just beyond the NE limb of the sun.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low to low.  There is a slight chance for a C-class flare from the
active area approaching the NE limb.
IIA.  Geophysical Activity Summary 29/2100Z to 30/2100Z:
The geomagnetic field was quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet for days one and two (01-02 May).  Quiet to
unsettled levels, with isolated active conditions, are expected on
day three (03 May) as a recurrent coronal hole high speed stream
becomes geoeffective.
