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.

SUBJ: IPS GEOMAGNETIC DISTURBANCE WARNING 15/30
ISSUED AT 0132UT/30 JULY 2015
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
01 Aug: Minor storm declining to unsettled.
SUBJ: IPS AURORA WATCH
ISSUED AT 0139 UT ON 30 Jul 2015 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
A high speed solar wind stream from a coronal hole is expected to
impact the Earth from 31 July. There is some possibility of seeing
auroras on high latitudes on 31 July and 1 August during local night
time hours. Aurora alerts will follow should favourable space weather
activity eventuate.
