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 195 Issued at 2200Z on 14 Jul 2009IA. Analysis of Solar Active Regions and Activity from 13-2100Z to 14-2100Z Solar activity was very low. No flares were detected.
The visible disk remains spotless.
IB. Solar Activity Forecast
Solar activity is expected to remain
very low for the next three days (15-17 July).
IIA. Geophysical Activity Summary 13-2100Z to 14-2100Z
The geomagnetic field ranged from quiet to active levels during the
past 24 hours. In particular, active periods were observed from
0000-0600Z due to intermittent periods of southward IMF Bz (-9 nT)
accompanied by a coronal hole high-speed stream. The average speed
of the high-speed stream was about 530 km/s.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to decline to quiet levels and remain quiet for the next
three days (15-17 July).
