Solar Activity Report for 6/14/02
- The continued low level of activity is becoming a bit of a story in
itself. The sunspot number is quite low, and is similar to something
you would expect to see close to the solar minimum instead of the
solar maximum. Only a mildly elevated solar wind speed and density is
serving to break the doldrums. At present, there are 4 numbered
sunspot groups visible. Of those, 9991 could conceivable generate a
low-level M-class flare. When 9987 finishes rotating out of view,
there will only be 3 sunspot groups, and the sunspot number could drop
The current solar and geomagnetic conditions are :
NOAA sunspot number : 102
SFI : 131
A index : 5
K index : 2
Solar wind speed : 350.8 km/sec
Solar wind density : 5.4 protons/cc
Solar wind pressure : 1.0 nPa
IMF : 3.4 nT
IMF Orientation : 0.8 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 low. Region 9987 and 9991 have the
potential of C- and low level M-class events. Old Region 9963 (N17, L=
318) is due to return on day two of the forecast period.
Geomagnetic activity forecast :
The geomagnetic field is expected to be a quiet to unsettled levels.
Isolated active conditions are possible on day one of the forecast
period due to coronal hole effects.
Recent significant solar flare activity :
