2287Solar Activity Report for 8/4/04
- Aug 4 9:42 PMConditions remain quiet. Actually, they are very quiet, with an K
index of 0! There are two sunspot regions visible. Region 655, which
has grown a bit over the last day or so, has a small chance of
producing a significant flare, but judging from the background X-ray
flux plot, I wouldn't hold my breath. We could see a brief increase
in the solar wind speed on the 7th due to the effects of a small
coronal hole. The most interesting news right now is what we can't
see directly. Sunspot region 649, which unleashed X-class flares the
last time around, appears to be holding together during it's transit
across the back side of the sun. It'll be coming back into view on or
about the 7th, so stay tuned for that.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 62
SFI : 85
A index : 5
K index : 0
Solar wind speed : 278.1 km/sec
Solar wind density : 0.1 protons/cc
Solar wind pressure : 0.1 nPa
IMF : 3.2 nT
IMF Orientation : 0.4 nT North
GOES-12 Background X-ray Flux Level : A7
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 at very low levels.
Geomagnetic activity forecast :
The geomagnetic field is expected to be at quiet levels through 06
Aug. Beginning on 07 Aug, periods of active levels are likely with a
slight chance for an isolated active event due to the influence of a
high speed solar wind stream.
