The geomagnetic storms of the 9th were nowhere near as effective as the 7th and
8th, but a few faint aurora were seen by dedicated observers
The
Australian IPS has issued a Geomagnetic Disturbance Warning and the NOAA site
has a predicted G1 storm from a fast moving solar wind stream from a coronal
hole. Unlike the previous coronal holes this is from the suns northern
hemisphere and will most likely just graze us, with much less likelihood of an
aurora. The arrival of the solar wind stream will be anywhere between the early
morning of the 13th Australian time, to the evening of the 13th.
Dark sky
sites have the best chance of seeing anything, and always allow around 5 minutes
for your eyes to become dark adapted.
As always look to the south for
shifting red/green glows, beams have been reported consistently over the last
few aurora and a large green "blob" has been seen.
The all sky aurora
camera in Northern Tasmania at Cressy may be helpful.

SUBJ: IPS
GEOMAGNETIC DISTURBANCE WARNING 15/46
ISSUED AT 2320UT/11 OCTOBER 2015
BY
THE AUSTRALIAN SPACE FORECAST CENTRE.
Due to the angle of the leading
edge of the coronal hole it is
uncertain when it will be geoeffective, most
likely late in the
UT day, 12 October, or tomorrow, 13
October.
INCREASED GEOMAGNETIC ACTIVITY EXPECTED
DUE TO CORONAL HOLE
HIGH SPEED WIND STREAM

Hi Ian, we are looking forward to this one tonight. Here's hoping.
