Solar Activity Report for 5/10/02
- The solar wind speed and density are elevated this evening in the wake
of yesterday's impact of the somewhat weak full-halo CME that was
generated by the M-class flare of 5/8. The impact was a fairly mild
one, and did not generate any widespread geomagnetic storm conditions
or aurora. With no new significant flare or coronal hole activity,
things are quiet this evening. Sunspot region 9934 remains a threat
for M-class flares as it closes in on the western limb of the solar disk.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 245
SFI : 191
A index : 13
K index : 1
Solar wind speed : 348.1 km/sec
Solar wind density : 9.1 protons/cc
Solar wind pressure : 1.8 nPa
IMF : 4.5 nT
IMF Orientation : 2.9 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 :
Space weather for the next 24 hours is expected to be minor. Radio
blackouts reaching the R1 level are expected.
Solar activity forecast :
Solar activity is expected to be low to moderate. Region 9934 appears
quite capable of producing M-class flare activity
Geomagnetic activity forecast :
The geomagnetic field is expected to be at quiet to unsettled levels.
Recent significant solar flare activity :
