Geomagnetic Disturbance Warning (16 October)

The Australian IPS has issued a Geomagnetic Disturbance Warning and the NOAA site has a predicted G1 storm from a fast moving solar wind stream from a coronal hole. Like the previous coronal hole warning there is not much likelihood of an aurora, but with dark skies it is worth keeping an eye out. The arrival of the solar wind stream will be anywhere between the evening of the 16th to the morning of the 17th Australian time.

Dark sky sites have the best chance of seeing anything, and always allow around 5 minutes for your eyes to become dark adapted.


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

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.

The all sky aurora camera in Northern Tasmania at Cressy may be helpful.
