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 126 Issued at 2200Z on 06 May 2002

IA. Analysis of Solar Active Regions and Activity from 05-2100Z to 06-2100Z

Solar activity was at low levels. The largest event was a optically uncorrelated C2/1f flare at 06/1604 UTC. Region 9934 (S17E08) has shown slight decay and has simplified to a beta-gamma magnetic configuration. At 06/1350 UTC a partial halo CME appeared in SOHO/LASCO C2 imagery on the east limb. Analysis of EIT, GOES X-Ray, and H-alpha data indicate a probable backside event.
IB. Solar Activity Forecast
Solar activity is expected to be at low levels. Region 9934 has lost it's delta configuration in the leader spot.
IIA. Geophysical Activity Summary 05-2100Z to 06-2100Z
The geomagnetic field was quiet to active levels. One 3-hour period (15-18 UTC) was at active levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels. Unsettled conditions are expected for day one of the forecast period.
