Solar Activity Report for 2/10/05
- The Earth is inside of a high speed solar wind stream, but it isn't
having much of an effect. While being high speed, it is also quite
tenous, at about one proton per cc. That isn't dense enough to have a
significant effect on the geomagnetic field. There are currently four
small sunspot regions in view, with a fifth on the verge of rotating
into view. None of the ones currently visible have the abilitty to
generate a significant flare at this time. Don't be surprised if G-1
geomagnetic storm conditions appear briefly over the next couple of
days, but I don't expect to see anything major, and aurora seem
unlikely for now.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 63
SFI : 114
A index : 18
K index : 2
Solar wind speed : 623.7 km/sec
Solar wind density : 1.4 protons/cc
Solar wind pressure : 1.1 nPa
IMF : 3.6 nT
IMF Orientation : 0.5 nT North
GOES-12 Background X-ray Flux level : B2
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.
Geomagnetic activity forecast :
The geomagnetic field is expected to be quiet to active on 11
February. Expect quiet to unsettled conditions on 12 and 13 February
as the coronal hole stream moves out of geoeffective position.
