Solar Activity Report for 2/12/03
- The general scene is fairly quiet this evening, although the solar
wind density is somewhat higher than normal, and to tell you the
truth, I have no idea why. There haven't been any major flares, and
no Earth-directed CME's have been produced within the last 48 hours.
Barring any unforseen events, things should remain pretty boring for
the next couple of days. None of the sunspot regions visible look to
have any significant flare producing potential. Around the 15th or
so, however, activity should pick up a bit. There is a coronal hole
that is rotating into an Earth-pointing position. The solar wind
gusts from it should be arriving on or about the 15th.
The current solar and geomagmetic conditions are :
NOAA sunspot number : 119
SFI : 132
A index : 9
K index : 2
Solar wind speed : 393.6 km/sec
Solar wind density : 10.0 protons/cc
Solar wind pressure : 3.1 nPa
IMF : 11.4 nT
IMF Orientation : 0.8 nT South
Conditions for the last 24 hours :
No space weather storms were observed for the past 24 hours.
Forecast for the next 24 hours :
No space weather storms are expected for the next 24 hours.
Solar activity forecast :
Solar activity is expected to be at low levels.
Geomagnetic atcivity forecast :
The geomagnetic field is expected to be quiet to unsettled. Day three
may experience isolated active periods due to an anticipated favorably
positioned transequatorial coronal hole.
Recent significant solar flare activity :
