Worth noting that Kp, which many talk about in discussions online, is more or less useless for anyone in Australia or the southern hemisphere. Lots of beginner Aurora chasers here get tripped up by that.

What is useful is KAus and the G index, KAus is shown on this page, so thats what i'll be tracking.

Are there any resources to track Aurora sightings or predicted sightings?

https://aurora-alerts.uk/ Ignore the UK TLD, this tracks global sightings

Ahh thank you! I saw a few photos from last night's Aurora sightings down here in Vic, Australia. Maybe next time! :)

At the bottom right of that page is a subscribe link, with a number of different alerts and lists to subscribe to.

Thank you!

Is that tonight or last night?

It was only issued this morning Australian time, so I presume it's for tonight.
