Solar Activity Report for 6/13/04
- Activity is beginning to pick up as a new active sunspot region,
reegion 634, is rotating into view. It has already fired off an
M-class flare, and the background X-ray flux has risen significantly.
Region 634 isn't in a position yet to see exactly how big it is or
what sort of magnetic complexity it has, but that will change over the
next few days. There's also a small coronal hole that has rotated
into an Earth-pointing position. We should begin seeing the high
speed colar wind gusts from it on or about the 18th.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 55
SFI : 95
A index : 9
K index : 3
Solar wind speed : 319.6 km/sec
Solar wind density : 1.0 protons/cc
Solar wind pressure : 0.2 nPa
IMF : 8.4 nT
IMF Orientation : 8.3 nT South
GEOS-12 Background X-ray Flux level : B3
Conditions for the last 24 hours :
Space weather for the past 24 hours has been minor. Radio blackouts
reaching the R1 level occurred.
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. Another small
M-class flare is possible in Region 634.
Geomagnetic activity forecast :
The geomagnetic field is expected to be quiet to unsettled becoming
unsettled to active under the influence of a high-speed coronal hole
