Geomagnetic Alert (3 September) G1 storm in progress
The Australian Space Weather Service (SWS ) has issued a Geomagnetic Alert for
3 September as there is a G1 storm in progress with a Kp of 5. The Hobart
magnetometer is showing a promising Kindex of 6, other parameters less enticing Velocity: 663 km/sec Bz: -1.0 nT Density = 6.0 p/cc but aurura were seen last
night under these conditions. It is likely that conditions will be unsettled and
swing about in the evening with brief bursts of aurora in Tasmania (and possibly
camera only in Southern Victoria) and long quite periods of quiet. Evening and
morning skies are Moon free, but cloud is problematic. 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, as well as bright proton arcs and "picket fences".
As don't forget the continuing "Planet dance". If you are going out in the dusk, Venus Jupiter and Mercury are hovering in a triangle above the western horizon,with the Moon in the venter of the triangle. Mars , Saturn and the red star Antares form a matching triangle higher in the western sky.
Here is the near-real time satellite view of the clouds http://satview.bom.gov.au/
Cloud cover predictions can be found at SkippySky.
The all sky aurora camera in Northern Tasmania at Cressy is currently borked
