The solar wind speed has dropped back to normal levels since the most
recent round of actvity. At least one person managed to capture a
picture of aurora shining through the midnight sun twilight in Alaska,
as can be seen here.
Sunspot region 756, while still large enough to be naked-eye visible,
is decaying in size and magnetic complexity. It never did manage to
fire off a significant flare, although it did ccome darn close a
couple of times, generating two C-9 events. It will soon be rotating
out of view. The next noteworthy event will be another coronal hole
solar wind stream encounter. A medium-sized coronal hole has rotated
into an Earth-pointing position, and we should see the solar wind
gusts from it in four or five days.
The current solar and goemagnetic conditions are :
NOAA sunspot number : 50
SFI : 109
A index : 6
K index : 1
Solar wind speed : 335.5 km/sec
Solar wind density : 1.2 protons/cc
Solar wind pressure : 0.3 nPa
IMF : 4.4 nT
IMF Orientation : 2.5 nT North

Conditions for the past 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 low with predominately B and C-class
activity in Regions 756 and 758. There is a chance of a small M-class
flare in either of these regions, as well.
Geomagnetic activity forecast :
The geomagnetic field is expected to be quiet to unsettled.
