Solar Activity Report for 11/2/02
- ** Aurora Watch In Effect **
The Earth should soon be entering a coronal hole generated high speed
solar wind stream, and an aurora watch is in effect for that reason.
We should start seeing the effects either Sunday or Monday. A strong
south tilt to the Interplanetary Magnetic Field has caused the
geomagnetic field to be somewhat active today, actually reaching the
G-1 geomagnetic storm level at one point. If the IMF retains its
south-pointing orientation when the high-speed solar wind hits, things
could be quite interesting. The are several sunspot regions visible
on the solar disk. Sunspot region 177 looks like it is the only one
to have any flare generating potential for the time being.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 177
SFI : 165
A index : 22
K index : 2
Solar wind speed : 484.6 km/sec
Solar wind density : 5.2 protons/cc
Solar wind pressure : 2.3 nPa
Conditions for the last 24 hours :
Space weather for the past 24 hours has been minor. Geomagnetic storms
reaching the G1 level occurred.
IMF : 10.5 nT
IMF Orientation : 9.0 nT South
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 177 has the
potential to produce an isolated M-class event.
Geomagnetic activity forecast :
The geomagnetic field is expected to be predominately unsettled to
active for the next three days in response to a recurring coronal
Recent significant solar flare activity :
