Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 154 Issued at 2200Z on 03 Jun 2010
IA.  Analysis of Solar Active Regions and Activity from  02/2100Z
to 03/2100Z:  Solar activity has been at very low levels for the past
24 hours. Region 1076 (S19W36) has grown in size and is magnetically
classified as a beta group. No new regions were numbered today.
IB.  Solar Activity Forecast:  Solar activity is expected to remain
at very low levels with a slight chance for C-class events for the
next three days (04-06 June).
IIA.  Geophysical Activity Summary 02/2100Z to 03/2100Z:
The geomagnetic field ranged from quiet to active levels at mid
latitudes with isolated storm periods from 0900Z-1500Z at high
latitudes. Observations from the ACE spacecraft indicate a
continuation of a high speed solar wind stream, with an increase in
solar wind speed from 450 km/s to 550 km/s. The greater than 2 MeV
electron flux at geosynchronous orbit was at high levels.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet to unsettled levels with a slight chance for
isolated active periods for the next two days (04-05 June). 
Activity is due to a recurrent coronal hole high speed stream on day
one and the arrival of a CME observed on 31 May on day two.
Predominantly quiet conditions are expected on day three (06 June).
