Solar Activity Report for 1/31/03
- ** Aurora Watch In Effect **
The Earth is now inside of a coronal hole high speed solar wind
stream, and G-1 geomagnetic storm conditions have been observed within
the last 24 hours. Therefore, an aurora watch is in effect.
Skywatchers in the higher latitudes should keep an eye to the sky for
aurora. Other than that, there isn't much happening as solar activity
remains low. There are three small numbered sunspot regions visible,
but none appear to have any significant flare generating capability at
the present time.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 49
SFI : 94
A index : 10
K index : 2
Solar wind speed : 627.9 km/sec
Solar wind density : 2.1 protons/cc
Solar wind pressure : 1.6 nPa
IMF : 6.8 nT
IMF Orientation : 1.6 nT North
Conditions for the last 24 hours :
Space weather for the past 24 hours has been minor. Geomagnetic storms
reaching the G1 level occurred.
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 low. Additional small flares are
expected in Region 549. There is a chance of a small M-class flare in
this region as well.
Geomagnetic activity forecast :
The geomagnetic field is expected to be mostly unsettled to active
with the possibility of isolated minor storm periods as the coronal
hole induced disturbance continues.
Recent significant solar flare activity :
