Geomagnetic Warning (18-19 November)
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, and in quite a few of the recent ones we have had white "proton arcs".
Here is the near-real time satellite view of the clouds http://satview.bom.gov.au/
Cloud cover predictions can be found at SkippySky.
The all sky aurora camera in Northern Tasmania at Cressy may be helpful.
Geomagnetic conditions are expected to rise from quiet to minor
storm levels on 18 November due to the expected effect of a high
speed solar wind stream from a coronal hole and possible glancing
blow from the CMEs observed late on 15 and early on 16 November.
This coronal hole effect may keep the conditions enhanced to
unsettled to minor storm levels on 19 November.
INCREASED GEOMAGNETIC ACTIVITY EXPECTED
DUE TO CORONAL HOLE HIGH SPEED WIND STREAM
FROM 18-19 NOVEMBER 2015
GEOMAGNETIC ACTIVITY FORECAST
18 Nov: Quiet to minor storm
19 Nov: Unsettled to minor storm

May explain some of the interesting phenomenon captured over Melbourne yesterday evening.
Through the inner city haze at 6pm you could see part of a red sun.
A strange hazy "cloud "cover had the effect where it filtered &broke the red sun shape into a red Triangle shape then a crescent so that only parts of this setting? Sun -a very red sphere -was visible at a time.
Took a great photo -the atmosphere and this hazy big cloud filter suddenly diminished and this red sun sphere clearly shows 3 yellow fiery sections in patches.
It is an interesting photo.
If looking for portents this fitted the bill :) However sun spot storms have also linked to geothermal activity - commonly known as earthquake weather. Should be interesting to see if this is the case.
Thx for the interesting blog: KatyQ
Sadly, those wonderful optical effects were the haze from the terrible bushfires in Western Australia, thinning sections of the haze are responsible for the different brightness of the regions of the Sun. Very spectacular, but caused by a tragic circumstance.
