Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 200 Issued at 2200Z on 19 Jul 2010
IA. Analysis of Solar Active Regions and Activity from 18/2100Z
to 19/2100Z: Solar activity was very low. Region 1087 (N17W61)
produced a long duration B5 flare at 19/0752Z. This region shows a
continued sign of decay. New Region 1089 (S23E70) was numbered
today and emerged on the disk as a beta magnetic configuration.
IB. Solar Activity Forecast: Solar activity is expected to be very
low with a slight chance for a C-class event.
IIA. Geophysical Activity Summary 18/2100Z to 19/2100Z:
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be predominantly quiet for days one and two (20-21
July). Quiet to unsettled conditions are expected for day three (22
July) as a recurrent coronal hole high speed stream will be in a
geoeffective position.
