[Aurora Alert] Geomagnetic warning and Aurora Watch (1-3 June)
If these geomagnetic events occur and result in aurora they could be seen from Tasmania weather permitting. The Moon is waxing to full and will significantly interfere with seeing aurora. Be patient, as the activity may rise and fall of the magnetic polarity of the wind may fluctuate significantly.
This event is unlikely to be spectacular, but still worth a look as viewing conditions are good.
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". A double arc, blobs, and curtains were seen in Septembers aurora last despite the moonlight.
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 still not available.
SUBJ: SWS GEOMAGNETIC DISTURBANCE WARNING 18/11
ISSUED AT 0005UT/30 MAY 2018
BY THE AUSTRALIAN SPACE FORECAST CENTRE.
On 1 June geomagnetic activity is expected to increase to Active
and Minor Storm levels due to arrival of the corotating interaction
region and high-speed solar wind streams associated with the
recurrent trans-equatorial coronal hole.
INCREASED GEOMAGNETIC ACTIVITY EXPECTED
DUE TO CORONAL HOLE HIGH SPEED WIND STREAM
FOR 01 JUNE 2018
GEOMAGNETIC ACTIVITY FORECAST
01 Jun: Active
SUBJ: SWS AURORA WATCH
ISSUED AT 2347 UT ON 30 May 2018 by Space Weather Services
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
A coronal hole is rotating into a geoeffective position that is
favourable for possible Auroral activity. There is an increased chance
of Auroral activity between 1 June and 3 June. Warnings and/or alerts
will follow if significant geomagnetic activity actually occurs.
Visit the SWS Aurora webpage http://www.sws.bom.gov.au/Aurora for current
aurora viewing conditions.
Our Aurora forecasting tool, located at
http://www.sws.bom.gov.au/Aurora/3/1, may help to estimate regions
from where aurora would be visible.
