Possible Aurora Australis 8th-9th March 2012

Back in 2003 I was lucky enough to see and photograph bright pink and green Aurora Australis (see more aurora australis photo's here at my personal website) from suburbs of Perth and from the Wheatbelt of Western Australia. Ever since I've been hoping for another chance ... it looks like we are finally getting that chance as the Sun increases its solar activity.

There is a lot of talk today about the possibility of Aurora's due to the recent large X5 solar flare released by the Sun, and tonight there's a real chance of seeing aurora.

Aurora's are caused by the interactions between particles from the Sun and our atmosphere. When there's more particles coming from the Sun such as from a X5 flare, there is more chance of an Aurora.

The best chance you have to see an Aurora is being in dark skies at "high" latitudes in the next 24 hours. High latitudes are those closer to the poles (north or south). Unfortunately we are near full moon now, meaning that the bright sunlight reflected by the Moon will wash out fainter aurora. At the moment it looks possible southern states (southern latitudes) of Australia might get a hint of aurora activity in the next 24 hours, so keep an eye out tonight!

Thanks to Ian Musgrave via the Southern-Aurora network for the information.

  1. No luck with the aurora here in Perth last night, unfortunately. If anyone had success it would be great to hear!

  2. Another update - Last night (9th March at approx 14:00 UT) we had Aurora Australis strong enough for me to clearly capture it in photographs from the Perth outer suburbs even with a full moon! It would have been spectacular without the Moon. Pics to come once ready. There is a prediction of more to come tomorrow (06:49 UT 11th March +/-7 hours), wait and see what that brings!
