Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 137 Issued at 2200Z on 16 May 2008
IA.  Analysis of Solar Active Regions and Activity from  15/2100Z
to 16/2100Z:  Solar activity was at very low levels.  New regions 994
(S11E04), 995 (N12E22), and 996 (N13E59) were numbered today. 
Regions 994 and 995 are simple A-type groups with a single spot. 
Region 996 is a B-type group with a beta magnetic configuration.
IB.  Solar Activity Forecast:  Solar activity is expected to remain
at very low levels.
IIA.  Geophysical Activity Summary 15/2100Z to 16/2100Z:
The geomagnetic field was at quiet levels.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet levels for days one and two of the forecast
period (17 and 18 May).  Geomagnetic activity is expected to
increase to quiet to unsettled levels with a slight chance for
active conditions on day three (19 May), as a coronal hole high
speed stream rotates into a geoeffective position.
