Solar activity report
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 200 Issued at 2200Z on 19 Jul 2010IA. 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.
