Geomagnetic warning and Aurora Watch (16-17 July)
The Australian Space Weather Service (SWS) has now issued a Geomagnetic Alert an Aurora Watch for possible aurora for 16-17 July (UT)
due to an impact from a coronal Mass Ejection. This is expected to arrive late
in the UT day on the 16th (which is the morning of the 17th Australian time).
The Space Weather Prediction Service has predicted a G1-G2 storm on July 16 UT (with most of the action on the morning f the 17th, probably extending into the evening of the 18th AEST if we are lucky). If these geomagnetic events occur and result in aurora they could be seen from Tasmania and Southern Victoria, weather permitting. The Moon is waning, and present in the early morning so will only modestly interfere with morning aurora. Be patient, as the activity may rise and fall of the magnetic polarity of the wind may fluctuate significantly.
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, as well as bright proton arcs and "picket fences".
Here is the near-real time satellite view of the clouds http://satview.bom.gov.au/

A new aurora camera is being installed at Campania, Tasmania. A live feed of the images from this camera is expected to be operational by the end of July 2017 .
SUBJ: SWS GEOMAGNETIC DISTURBANCE WARNING 17/34
ISSUED AT 0010UT/15 JULY 2017
BY THE AUSTRALIAN SPACE FORECAST CENTRE.
Geomagnetic conditions may rise to minor storm levels late on
16 Jul. Geomagnetic activity is expected to remain enhanced to
active to minor storm levels with the possibility of major storm
periods on 17 Jul due to CME effects.
INCREASED GEOMAGNETIC ACTIVITY EXPECTED
DUE TO CORONAL MASS EJECTION
FROM 16-17 JULY 2017

SUBJ: SWS AURORA WATCH
ISSUED AT 0230 UT ON 15 Jul 2017 by Space Weather Services
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
A Coronal Mass Ejection(CME) is anticipated to impact the Earth late
in the UT day of 16 July (Monday morning AEST). Aurora sightings
possible for Southernmost Australian regions should the CME arrive
earlier than anticipated. Aurora alerts will follow if significant
geomagnetic activity actually occurs.
