** Aurora Watch In Effect **
Just about any time now, the Earth should slide into a coronal hole
high speed solar wind stream. The solar wind speed has topped the 500
km/sec mark, but judging from the position of the coronal hole, I
expect to see higher speeds that we have at the moment. Aurora are a
possibility, and an aurora watch is in effect. If things hold true to
form, there should be a spike in the geomagnetic activiy when the
Earth crosses the boundary of the high speed solar wind stream. Stay
tuned, as I really don't think that's happened yet. Then again, as
coronal holes go, this one isn't particularly large, so I could be
wrong. We should know more on Monday. The flare outlook remains the
same as my last report, with no significant flare observed or predicted.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 124
SFI : 108
A index : 14
K index : 3
Solar wind speed : 537.4 km/sec
Solar wind density : 2.1 protons/cc
Solar wind pressure : 0.8 nPa
IMF : 9.0 nT
IMF Orientation : 4.5 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 very low to low. Regions 448 (N20W20)
and 449 (S16E13) may produce isolated C-class flares.
Geomagnetic activity forecast :
Geomagnetic activity is expected to be at quiet to active levels, with
isolated minor storm conditions, as a coronal hole continues to move
into geoeffective position.
