Solar Activity Report for 10/02/02
- ** G-2 Geomagnetic Storm In Progress **
** Aurora Watch In Effect **
The last couple of nights have seen quite a bit of geomagnetic
activity, and its not over yet! The Earth is still inside of a
coronal hole generated solar wind stream, and the Interplanetary
Magnetic Field has been south-pointing much of the time. At one point
the geomegnetic storm conditions were up to the G-3(strong) level.
Aurora have been seen and photographed as far south as Arizona. See
this link for some great aurora pictures from numerous locations
across Europe, Canada, and the US. The current level of activity is
forecasted to last at least one more day, and more aurora are possible
tonight. Meanwhile, sunspot region 134 continues to be a threat for
flares, and sunspot region 137 looks like it could also be a

storms reaching the G3 level occurred. Radio blackouts reaching the R1
Forecast for the next 24 hours :
Space weather for the next 24 hours is expected to be minor.
Geomagnetic storms reaching the G1 level are expected. Radio blackouts
reaching the R1 level are expected.
Solar activity forecast :
Solar activity is expected to be low to moderate. A chance for an
isolated M-class event exists from Region 134 (N13W29) and Region 137.
Geomagnetic activity forecast :
The geomagnetic field is expected to be at quiet to active levels
through the first day of the forecast period. Quiet to unsettled
conditions are expected for the remainder of the forecast.
