Aurora Alert 8-9 May, 2016


Launceston K-Index plot diagram

(Yes, this is the first alert since January) The Australian Space Weather Service (SWS ) has now  issued a  Geomagnetic Warning and Geomagnetic Alert for geomagnetic storms on 8-9 January UT from a coronal hole. A G3 storm occurred during daylight, the global Kp index is currently 6, and the Launceston Kindex is 5. Aurora are currently visible in New Zealand. The NOAA site has a predicted G1/G2 storm for tonight. If the current conditions persist there is a possibility we will get unaided eye visible aurora in Tasmania and  possibly the Southern mainland. Evening and morning skies are Moon free,  but currently most of Southern Australia is covered in thick cloud.

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".

Here is the near-real time satellite view of the clouds http://satview.bom.gov.au/
