Solar activity has increased some over the last 24 hours, and a long
period of no significant flares was broken by sunspot region 554,
which fired off an M-class flare on the 8th. Things are fairly quiet
for the time being, although that may be changing soon. A coronal
hole has rotated into an Earth-pointing position, and we should begin
to see the high speed solar wind gusts from it on or about the 12th.
Sunspot regions 551 and 554 have the potential to produce an M-class
The current solar and geomagnetic conditions are :
NOAA sunspot number : 81
SFI : 118
A index : 6
K index : 2
Solar wind speed : 369.3 km/sec
Solar wind density : 3.1 protons/cc
Solar wind pressure : 0.9 nPa
IMF : 4.1 nT
IMF Orientation : 3.8 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 at low to moderate levels. Regions
551 and 554 both have the potential to produce M-class flare activity.
Geomagnetic activity forecast :
The geomagnetic field is expected to be at quiet to unsettled levels.
12 February may experience active conditions due to a solar sector
boundary crossing, preceding an anticipated recurrent high speed
coronal hole stream.
