Solar Activity Report for 1/23/03
- ** Aurora Watch In Effect **
The high speed solar wind continues tonight, although the geomagnetic
storm of yesterday has died down for the time being. Nevertheless,
more geomagnetic activity is a distinct possibility as the solar wind
speed should stay elevated for at least the next 24 hours. Keep an
eye out for aurora around local midnight and afterwards, if you can
brave the cold, that is! Another duet of M-class flares was observed
today, this time from sunspot region 266. This region has exhibited
growth and signs of increasing magnetic complexity in the last 24
hours. Sunspot regions 263, 266, and 267 all have the potential for
producing an M-class flare.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 123
SFI : 136
A index : 18
K index : 4
Solar wind speed : 621.3 km/sec
Solar wind density : 5.0 protons/cc
Solar wind pressure : 2.8 nPa
IMF : 8.9 nT
IMF Orientation : 3.2 nT North
Conditions for the last 24 hours :
Space weather for the past 24 hours has been minor. Radio blackouts
reaching the R1 level occurred.
Forecast for the next 24 hours :
Space weather for the next 24 hours is expected to be minor.
Geomagnetic storms reaching the G1 level are expected. Radio blackouts
reaching the R1 level are expected.
Solar activity forecast :
Solar activity is expected to be at low to moderate levels. Region
263, 266 and 267 have the potential to produce and isolated M-class event.
Geomagnetic activity forecast :
The geomagnetic field is expected to be at unsettled to minor storm
levels. Continued high speed stream effects have the potential for
isolated minor storming on day one of the forecast period. Day two and
day three are expected to be quiet to unsettled.
