Solar Activity Report for 3/12/05
- View SourceAll is quiet tonight as the Earth has exited a high speed solar wind
stream, and the solar wind speed is back under 400 km/sec. There are
still three sunspot regions, but none of them look to have the
potential of generating s significant flare at this time. That's
about it for now. The lower parts of the sunspot cycle can be a bit
boring at times.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 67
SFI : 110
A index : 6
K index : 1
Solar wind speed : 352.9 km/sec
Solar wind density : 5.0 protons/cc
Solar wind pressure : 1.1 nPa
IMF : 2.4 nT
IMF Orientation : 0.3 nT South
GOES-12 Background X-ray Flux level : B1
Conditions for the last 24 hours :
No space weather storms were observed for the past 24 hours.
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. Some possibility
remains that Region 741 or 742 (S06E03) may produce C-class flares.
Geomagnetic activity forecast :
The geomagnetic field is expected to be quiet for the next three days.
A small coronal hole may produce elevated solar wind speeds on 14-15
March leading to possible unsettled to active conditions.
