Aurora Watch (31 July-1 August) and Blue Moon

An Aurora watch and a geomagnetic alert has been issued by the Australian  IPS for 31 July to 1 August due to  a coronal hole solar wind stream. This could translate into aurora at any time during the night time of the 17th to early morning 18th.  Aurora, if they flare up, are likely to be seen only in Tasmania (possibly Victoria).

Aurora can occur at any time after nightfall (although around midnight or just after seems to be common). 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.

Unfortunately, the light from the Full "Blue Moon" of 31 July will make seeing aurora hard.

The all sky aurora camera in Southern Tasmania at Cressy may be helpful.

BY THE AUSTRALIAN SPACE FORECAST CENTRE.

A high speed solar wind from a recurring coronal hole is expected
to raise the geomagnetic activity levels to minor storms on 31
July and 1 August.

INCREASED GEOMAGNETIC ACTIVITY EXPECTED
DUE TO CORONAL HOLE HIGH SPEED WIND STREAM
FROM 31 JULY 2015 TO 01 AUGUST 2015
_____________________________________________________________

GEOMAGNETIC ACTIVITY FORECAST
31 Jul:  Quiet to minor storm
