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 088 Issued at 2200Z on 29 Mar 2007

IA. Analysis of Solar Active Regions and Activity from 28-2100Z to 29-2100Z

Solar activity was very low. Solar X-rays remained below B-level during the past 24 hours. Region 949 (N06E48) is a small C-type group and is the only spotted group on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be very low.
IIA. Geophysical Activity Summary 28-2100Z to 29-2100Z
The geomagnetic field was quiet during the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet for the next two days (30-31 March). An increase to unsettled levels with a chance for active periods is expected sometime late on the third day (1 April) due to a recurrent high speed stream from a favorably positioned coronal hole.
