Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 038 Issued at 2200Z on 07 Feb 2008
IA. Analysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity was very low. No flares occurred. The visible disk remained spotless.
IB. Solar Activity Forecast: Solar activity is expected to be very low.
IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic field was quiet to unsettled. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during the period.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled during days 1 - 2 (08 - 09 Feb). Activity is expected to increase to unsettled to active levels on day 3 (10 Feb) due to a recurrent coronal hole high-speed stream.
III. Event Probabilities 08 Feb-10 Feb
IV. Penticton 10.7 cm Flux
V. Geomagnetic A Indices
VI. Geomagnetic Activity Probabilities 08 Feb-10 Feb
A. Middle Latitudes
B. High Latitudes
