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 060 Issued at 2200Z on 01 Mar 2007

IA. Analysis of Solar Active Regions and Activity from 28-2100Z to 01-2100Z

Solar activity was very low. There were no flares during the past 24 hours.
IB. Solar Activity Forecast
Solar activity is expected to be very low.
IIA. Geophysical Activity Summary 28-2100Z to 01-2100Z
The geomagnetic field ranged from active to quiet levels. Solar wind speed remained elevated due to a coronal hole stream, but gradually declined during the past 24 hours. The greater than 2 MeV electron flux reached high levels during the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet for the next three days.
