Solar Activity Report for 6/20/03
- Things are relatively quiet tonight, which is an exception to the rule
of how solar and geomagnetic activity has been of late. Sunspot
region 386 has been calm since it fired of an M6.8 flare on the 17th.
It does still, however, appear to have the ability to produce a major
flare. All of the recent activity has produced some beautiful aurora.
See this link for some great aurora pictures that have been captured
throughout the month of June, especially the 14th - 18th.

the forecasts pan out, there could be some more aurora activity
starting Saturday night as high-speed solar wind gusts from a coronal
hole arrive at Earth.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 121
SFI : 117
A index : 14
K index : 4
Solar wind speed : 567.2 km/sec
Solar wind density : 1.8 protons/cc
Solar wind pressure : 0.7 nPa
IMF : 6.8 nT

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 range from low to moderate levels.
Region 386 remains capable of producing an isolated major event.
Geomagnetic activity forecast :
The geomagnetic field is expected to be at predominantly unsettled
levels. Active conditions may exist especially at high latitudes
beginning late on day two with the return of a recurrent coronal hole
high speed stream.
