Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 183 Issued at 2200Z on 02 Jul 2010
IA. Analysis of Solar Active Regions and Activity from 01/2100Z
to 02/2100Z: Solar activity was very low during the past 24 hours.
Region 1084 (S20W06) produced a B1 flare at 01/2054Z.
IB. Solar Activity Forecast: Solar activity is expected to remain
very low throughout the forecast period (03-05 July).
IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z:
The geomagnetic field was quiet to unsettled with isolated active
periods at mid and high latitudes. The greater than 2 MeV electron
flux at geosynchronous orbit reached high levels during the past 24
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet to unsettled with a slight chance for an
isolated active period on day 1 (03 July). Mostly quiet conditions
are expected for days 2 and 3 (04-05 July) as the effects from the
recurrent coronal hole high speed stream subside.
