Solar Activity Report for 3/6/03
- ** Aurora Watch In Effect **
The high speed solar wind persists this evening, hovering close to the
500 km/sec mark, and an aurora watch remains in effect. Skywatchers
in the higher latitudes should be on the lookout for aurora.
Geomagnetic storm conditions at the G-1 level have been observed
within the last 24 hours. The high speed solar wind is now expected
to last for at least another 24 hours. Although solar activity has
remained quiet over the last few days, sunspot region 296 has at least
an outside change of producing an M-class flare.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 132
SFI : 150
A index : 18
K index : 3
Solar wind speed : 483.7 km/sec
Solar wind density : 2.9 protons/cc
Solar wind pressure : 0.8 nPa
IMF : 5.3 nT
IMF Orientation : 4.5 nT South
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. Though unusually quiet for its
size and complexity, Region 296 has potential for a C-class flare and
a slight chance for an M-class event. Minor C-class flares are also
possible in Region 301.
Geomagnetic activity forecast :
The geomagnetic field is expected to begin the period at unsettled to
active levels, but should gradually decline to mostly quiet to
unsettled levels by day two. Isolated active periods are likely on
days two and three.
Recennt significant solar flare activity :
