Solar Activity Report for 3/10/03
- All is basically quiet this evening as we await the arrival of the
next round of high speed solar wind gusts, which is expected on or
about the 15th. The associated coronal hole is in better view now,
and it looks to be a decent fairly sized one. The sunspot number is
staying above the 200 mark, and there are now six numbered sunspot
regions visible. Of the group, regions 296 and 306 look like they
have the best potential for producing an M-class flare.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 214
SFI : 144
A index : 11
K index : 3
Solar wind speed : 402.0 km/sec
Solar wind density : 2.5 protons/cc
Solar wind pressure : 0.8 nPa
IMF : 7.6 nT
IMF Orientation : 4.6 nT North
Conditions for the last 24 hours :
No space weather storms were observed for the past 24 hours.
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 at low levels.
Geomagnetic activity forecast :
The geomagnetic field is expected to be at quiet to unsettled levels
through the first 48 hours of the period. Day three should experience
active conditions due to a co-rotating interactive region that has
preceded a recurrent coronal hole over the past several rotations.
