Solar Activity Report for 7/10/02
- The Earth is still inside a coronal hole solar wind stream this
evening, and an aurora watch remains in effect. There were some
beautiful aurora seen over Quebec, Canada on the night of July 6th.

Sunspot region 19 is a threat for producing M-class flares, as is
sunspot region 30, which has just rotated into view. The enhanced
solar wind speed and density were are now seeing are expected to last
for at least the next 2 days.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 118
SFI : 129
A index : 8
K index : 2
Solar wind speed : 399.5 km/sec
Solar wind density : 5.6 protons/cc
Solar wind pressure : 1.4 nPa
IMF : 6.5 nT
IMF Orientation : 3.9 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 :
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 low to moderate. Region 30 is a
potential source of M-class activity.
Geomagnetic activity forecast :
The geomagnetic field is expected to be quiet to unsettled for the
first day of the forecast period, then trend toward more active
conditions by the end of the period, under the expected influence of a
near-equatorial coronal hole.
