Solar Activity Report for 3/20/04
- There have been a pair of M-class flares in the past three days. One
came from sunspot region 574 and one from region 578. Neither
appeared to fire a CME in our direction. There is a small coronal
hole that is in an Earth-pointing position, but it's located too far
north on the solar disk to send us much in the way of high-speed solar
wind gusts. The solar wind speed and density are slightly elevated
tonight. Sunspot regions 574 and 578 have the potential for producing
more M-class flares.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 82
SFI : 114
A index : 13
K index : 3
Solar wind speed : 405.6 km/sec
Solar wind density : 6.4 protons/cc
Solar wind pressure : 1.8 nPa
IMF : 5.6 nT
IMF Orientation : 1.6 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 very low to low levels with a
slight chance of isolated moderate level activity. Region 578 has
C-class flare potential and a small chance of an isolated M-class flare.
Geomagnetic activity forecast :
The geomagnetic field is expected to be at quiet to unsettled levels.
Isolated periods of active conditions may occur on 21 March,
particularly during local night time hours.
