Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 180 Issued at 2200Z on 29 Jun 2011
IA.  Analysis of Solar Active Regions and Activity from  28/2100Z
to 29/2100Z:  Solar activity was very low.  There were four B-class
flares in the past 24 hours.  Region 1242 (N17W17) produced a B5/Sf
event at 0953Z and a B2 event at 1705Z.  Region 1240 (S18W81) was
unchanged but produced a B7 event at 0032Z and a B2 event at 1952Z. 
Region 1242 and Region 1243 (N16E50) appeared to be slowly growing
but were small and stable.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low with a chance for an isolated C-class flare.
IIA.  Geophysical Activity Summary 28/2100Z to 29/2100Z:
The geomagnetic field has been quiet. 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 quiet on day 1 (30 June), and quiet to unsettled on
days 2 and 3 (1 - 2 July).  The increase in activity is forecast due
to recurrence of a favorably positioned coronal hole.
