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 335 Issued at 2200Z on 30 Nov 2004

IA. Analysis of Solar Active Regions and Activity from 29-2100Z to 30-2100Z

Solar activity was low. There were three C-class events during the past 24 hours; A C2 at 29/2137 UTC from Region 707 (S14W12), a C4/Sf at 0658 UTC from Region 708 (N11E27), and a C1 at 1102 UTC from Region 707. Region 707 has shown only minor development during the day but does have some weak mixing of magnetic polarity in the trailer portion of the group.
IB. Solar Activity Forecast
Solar activity is expected to be low for the next three days (30 November - 02 December).
IIA. Geophysical Activity Summary 29-2100Z to 30-2100Z
The geomagnetic field was predominantly unsettled to active during the past 24 hours. Solar wind signatures show increasing velocity (600-650 km/s), declining density, enhanced temperature, and regular oscillations of the z-component of the interplanetary magnetic field, all consistent with the presence of a high speed stream driven by a coronal hole.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be unsettled to active for tomorrow (01 December) and partway through the 2nd day (02 December). Thereafter activity should begin to decline, with predominantly unsettled levels for the 3rd day (03 December).
