Solar Actviity Report for 3/3/04
- ** Aurora Watch In Effect **
The Earth is still inside of a high speed solar wind stream tonight,
and an aurora watch remains in effect. The activity has been fairly
subdued, however, and the only aurora sightings occurred on the night
of the 2/27 in northern Canada and Alaska. Nevertheless, G-1
geomagnetic storm conditions were observed within the last 24 hours,
so skywatchers in the higher latitudes should still keep an eye out
for aurora. Look for isolated active periods tomorrow, with a gradual
decline after than as the solar wind speed drops off. Of the two
numbered sunspot regions visible, sunspot region 567 looks to have at
least a small chance of generating as significant flare.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 42
SFI : 90
A index : 11
K index : 1
Solar wind speed : 571.1 km/sec
Solar wind density : 1.4 protons/cc
Solar wind pressure : 0.7 nPa
IMF : 3.9 nT
IMF Orientation : 2.8 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 low for the next three days (04-06
March). Region 567 is expected to produce additional C-class level
activity. There is a slight chance for an isolated M-class event.
Geomagnetic activity forecast :
The geomagnetic field is expected to be unsettled with some isolated
active periods for 04 March. Mostly unsettled levels are expected for
05 March and quiet to unsettled levels are expected for 06 March. The
decrease in activity is expected from the slow decline of the high
speed solar wind stream.
Recent significant solar flare activity :
