Aurora watch and GEOMAGNETIC WARNING June 5-6

The Australian Space Weather Forecasting Centre reports three coronal mass ejections (CMEs) have been observed associated with two M-class and one X-class flares from region 4455. Modelling indicates the second and third CMEs have an estimated arrival at Earth on 05-Jun at 10:00UT +/- 10 hrs (anywhere from 2pm the 5th AEST to 6 am the 6th AEST). G2 planetary geomagnetic conditions are expected, with a chance of G3.If storms eventuate, visible aurora may be seen in Tasmania and possibly southern parts of Victoria, South Australia and Western Australia during local night hours. The Moon is waning and heading towards Last Quarter. It will interfere with seeing aurora in the early morning.
