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 026 Issued at 2200Z on 26 Jan 2003

IA. Analysis of Solar Active Regions and Activity from 25-2100Z to 26-2100Z

Solar activity was at low levels. Region 268 (N15W42) produced a C2.6 flare at 26/1040 UTC. Region 268 has shown some decay in area coverage. Region 266 (S22W26) has grown in area coverage and maintains its beta-gamma magnetic configuration. Some weak polarity mixing was evident near the intermediate spots of Region 266. Three new regions were numbered today: Region 270 (S04W36), Region 271 (S06W21), and Region 272 (S05E26).
IB. Solar Activity Forecast
Solar activity is expected to be low. The majority of activity is expected to come from Region 266 and Region 268.
IIA. Geophysical Activity Summary 25-2100Z to 26-2100Z
The geomagnetic field was at quiet to active levels. Elevated solar wind speed near 700 km/s combined with a Bz near negative 5 nT resulted in active conditions.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels. Diminishing effects from the coronal hole are expected to produce only unsettled conditions.
