The Earth is inside a high speed solar wind stream this evening, which
was generated by a large coronal hole that crossed the sun's central
meridian a few days ago. Geomagnetic storm conditions are a
possibility for the next 24 hours, and skywatchers in the higher
latitudes should keep an eye out for aurora. Sunspot region 9845
remains a threat for M-class flares, although it has been quiet so
The current solar and geomagnetic conditions are :
NOAA sunspot number : 168
SFI : 172
A index : 14
K index : 2
Solar wind speed : 664.9 km/sec
Solar wind density : 2.1 protons/cc
Solar wind pressure : 1.5 nPa
IMF : 8.0 nT
IMF Orientation : 1.9 nT South
Conditions for the last 24 hours :
Solar activity was low. The geomagnetic field was quiet to active.
Stratwarm Alert exists Tuesday.
Forecast for the next 24 hours :
Solar activity will be low. The geomagnetic field will be quiet to
Solar activity forecast :
Solar activity is expected to be at low levels. Region 9845 continues
to be complex enough to possibly produce an isolated M-class flare.
Geomagnetic activity forecast :
The geomagnetic field activity is expected to be at quiet to active
conditions through day one of the forecast period. Due to coronal hole
effects, minor storm conditions may be possible at higher latitudes
through day one as well. Days two and three should see a return to
quiet to unsettled conditions.
