Solar Activity Report for 10/10/03
- It's not often you see a Planetary K index of 0, but that's what we
have tonight. That's just about as calm as you can get, folks! It's
actually somewhat unexpected, given that the solar wind speed is
hovering around the 400 km/sec mark, but a persistent north-pointing
Imterplanetary Magnetic Field has been in place for several days. In
about three days, however, activity should begin to pick up as the
Earth moves inside of a high speed solar wind stream coming from a
small coronal hole. None of the sunspot regions visible appear to
have any significant flare generating potential at the present time.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 93
SFI : 112
A index : 4
K index : 0
Solar wind speed : 410.1 km/sec
Solar wind density : 1.3 protons/cc
Solar wind pressure : 0.4 nPa
IMF : 5.4 nT
IMF Orientation : 0.6 nT North
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 to low levels.
Geomagnetic activity forecast :
The geomagnetic field is expected to be at quiet to minor storm
levels. The onset of a coronal hole high speed stream is expected on
day three with minor storm conditions possible.
Recent significant solar flare activity :
