Solar Activity Report for 12/22/04
- View SourceWe've actually had G-1 geomagnetic storm conditions observed within
the last 24 hours, although I don't have a clue as to why. There
haven't been any significant solar flares, nor are we in a coronal
hole solar wind stream. Perhaps we just went through a period where
the interplanetary magnetic field tilted south, which can trigger
geomagnetic storms. In fact, the IMF is carrying a slightly
south-pointing orientation as I write this. There is one numbered
sunspot group visible, but it doesn't appear to have the potential to
generate any significant flares.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 47
SFI : 99
A index : 18
K index : 1
Solar wind speed : 458.4 km/sec

Solar wind pressure : 0.2 nPa
IMF : 5.9 nT
IMF Orientation : 1.6 nT South
GOES-12 Background X-ray Flux level : B1
Conditions for the last 24 hours :
Space weather for the past 24 hours has been minor. Geomagnetic storms
reaching the G1 level occurred.
Forecast for the next 24 hours :
No space weather storms are expected for the next 24 hours.
Solar activity forecast :
Solar activity is expected to be very low to low.
Geomagnetic activity forecast :
The geomagnetic field is expected to be quiet to unsettled with
isolated periods of active conditions.
