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 242 Issued at 2200Z on 29 Aug 2004

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

Solar activity remains at very low levels. Region 663 (N07W59) has undergone little change, and remains a magnetically simple Beta-class region. Region 666 (N16E38) was numbered today.
IB. Solar Activity Forecast
Solar activity is expected to remain at very low levels through 01 Sep. Chances for some C-class and greater activity will increase on 01 Sep with the return of Region 656.
IIA. Geophysical Activity Summary 28-2100Z to 29-2100Z
The geomagnetic field has been at quiet to unsettled levels. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels today.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to remain at quiet to unsettled levels through 01 Sep.

VII. COMMENTS The ACE spacecraft orbit will bring ACE to its closest approach with the Sun on August 30, 2004. During that time possible solar radio noise may interfere with spacecraft telemetry resulting in the loss of real time solar wind plasma, magnetic field, and particle data.
