Not much to be missed really. We were out until the Bz went north radically and the Kp dropped away to 4. I captured a couple of nice beams but nothing really exciting and no visual sighting of anything. It was strange as As the Tassie website was showing KP at 7-6 for most of the night and a bz of around -14 to -11 until moon set and then it swung north. Just when it really mattered.

The is a CME going to hit about 3 am tomorrow morning and that is from the M6.5 full halo flare on the 22nd. So if you are keen it might fire up around 4-5am. Might venture out myself. Charging batteries now.

Pity I did not get up at 5am on the 23rd. Kicking myself now. Next time.

Thanks for the heads up Paul. I'm guessing it's impossible to see in the light pollution of Melbourne?

Billi, it just depends on the strength of the event. The height the Kp is up to (for you above 4 1/2 if the Bz is real low, and above 5 with a middling Bz, and the further into the (-) the -Bz is, then the more likely you are to see one.
Often you can photograph one without being able to see it.
Find a few places with a good southerly aspect without tall landscape features. And avoid light between you and it.
Put your camera on a tripod set at about 1600ISO, and 30~60secs at the widest aperture of a wide angle lens, and give it a go.
Strong moon light can wash out a weaker one, while 1/st and 2nd quarter can give you nice foreground nightscape details.
This page has all the info you need to get started, including the meters
http://www.aurora-service.net/aurora-forecast/ - it updates every minute (so on a smartphone you might get a jitter in the screen every minute)
Hope it helps

It'd be great if they could forecast the Aurora at least 6 months ahead, then I could book a trip to Tassie and see it a girl can dream! I'll definitely keep an eye on the Aurora Service page though, just in case

http://www.swpc.noaa.gov/node/45
This site is great because it has the 30 minute forecast (as Glen posted previously)

There was nothing last night Steve. Tuesday morning you would have been in luck.

I am hoping there is another big flare in the this cycle and we get the chance to see it here. We had a chance on Tuesday morning but the forecast was for cloud and rain. It did not say it would clear for five hours from 3am.

Today's forecast (27/6) is 5-6kp from UTC 12.00 - 00.00

Maybe at a pinch from down the south coast if it's not cloudy?

Well, it's a beautiful and clear sunny day here in NW Tasmania. Let's hope there is no photo worthy event tonight, so it stays lovely and clear.

Cos if I do this, then I get this . It's a proven weather phenomenon in Tas.

I have been saving a nightscape/aurora location for a big one because I believe;
a) it will be an icon picture, and
b) for a photographer friend from Sydney who visits every 3 months, or so.

She's here now for a week+ and it will be well worth the 40Klm drive to the site if it lights up. But everytime it looked good during a visit then.... I mean, the underside of clouds can be photographically interesting, but only if that's what you're aiming for.
Frustratedly Yours,
Trev

Is there anywhere that you can sign up to get an email alert if an auroral activity is high?

Not sure about email alerts, but there is a Facebook group called "Aurora Australis Tasmania Alert NOW" which sends out alerts whenever people post to that group upon actually seeing an aurora (I'm not sure, but I assume you need the Facebook app to activate the alerts - I am a member of that group but don't use the Facebook app).

There are also numerous phone apps that can provide SMS-like notifications.
