Joint USAF/NOAA Report of Solar and Geophysical Activity 29 Jan 2003
SDF Number 029 Issued at 2200Z on 29 Jan 2003
IA. Analysis of Solar Active Regions and Activity from 28/2100Z
to 29/2100Z: Solar activity was low. Just isolated small C-class
activity occurred, as the disk regions were either stable or
decaying. One new region emerged, 275 (S11W08).
IB. Solar Activity Forecast: Solar activity is expected to persist
at low levels.
IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z:
The geomagnetic field was quiet to active. One period of active
conditions was observed in the past 24 hours. The GOES greater than
2 MeV electron flux reached high levels during the day.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet to unsettled throughout the period.
