Solar Activity Report for 8/31/02
- Sunspot region 95 fired off a major X1.5 flare on Friday, continuing
the relatively active period that has been going for quite a while
now. A short-lived radio blackout over North America and Europe was
the result, although it doesn't look like their was a CME associated
with the event. More major flares are a possibility from this active
sunspot region, and solar activity is forecasted to remain at moderate
levels. A coronal hole has rotated into an Earth-pointing position.
We should start receiving high-speed solar wind gusts from it Monday
The current solar and geomagnetic conditions are :
NOAA sunspot number : 153
SFI : 180
A index : 12
K index : 4
Solar wind speed : 369.5 km/sec
Solar wind density : 3.8 protons/cc
Solar wind pressure : 0.7 nPa
IMF : 7.1 nT
IMF Orientation : 0.6 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 :
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 at moderate levels. Regions 87 and 95
have the potential to produce an isolated major flare.

- Thanks for the report, B-1.
Have been doing a lot on tropical storms and interesting how the
weekend SOI data just came in with -4.5 all weekend! I think
flaring/CME is leveling and we well start to see a tropical storm
season in the Atlantic. The next few months are going to be very
