Geomagnetic warning and Aurora Watch (8-9 July)
The Australian Space Weather Service (SWS) has now issued a Geomagnetic Alert an Aurora Watch for possible aurora for 8-9 July (UT) due
to solar wind from a coronal hole. This is expected to arrive late in the UT
day on the 8th (which is the morning of the 9th Australian time). The Space Weather Prediction Service has Predicted a G1 storm on July 9 UT. If these
geomagnetic events occur and result in aurora they could be seen from Tasmania
and Southern Victoria, weather permitting.
However, the Moon is nearly full, so will significantly interfere. 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/
Cloud cover predictions can be found at SkippySky.
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 17/33
ISSUED AT 0057UT/07 JULY 2017
BY THE AUSTRALIAN SPACE FORECAST CENTRE.
Expect an increase in geomagnetic activity late on UT day, 08
July due to influence of geoeffective coronal hole.
INCREASED GEOMAGNETIC ACTIVITY EXPECTED
DUE TO CORONAL HOLE HIGH SPEED WIND STREAM
FROM 08-09 JULY 2017

GEOMAGNETIC ACTIVITY FORECAST
08 Jul: Quiet to Active isolated cases of Minor Storm levels at higher
latitudes
09 Jul: Unsettled

ISSUED AT 0130 UT ON 07 Jul 2017 by Space Weather Services
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
Effects of a coronal hole are expected to impact the Earth within the
next 48 hours, possibly resulting in geomagnetic activity and visible
auroras during local nighttime hours at Tasmania latitudes. Aurora
alerts will follow if significant geomagnetic activity actually
occurs.
