Aurora Australis, Queenscliff Pier, Victoria. by 


Aurora Australis (or Southern Aurora) March 1990, from Queenscliff Pier, Victoria, Australia.
This aurora appeared out of the darkness unexpectedly just before driving back to Melbourne after a days outing. It’s sudden appearance grew and peaked in brightness in less than a minute and gradually diminished over about 10-15 minutes. The yellow/green band of light above the horizon is also aurora light.

Severe Geomagnetic Storm Intervals in History
And Future Prospects…

‘….Historically, some of the most intense geomagnetic and auroral storms have occurred during the declining years of the solar cycle. For example, the most severe geomagnetic storm on record occurred on 17 September 1941. That was 53 months after the solar maximum. In fact, this 1941 storm occurred during a time when the sun was closer to the solar minimum than the solar maximum. Severe geomagnetic storms have also occurred within just a few months of the Sun’s actual solar minimum as well, which confirms the fact that significant space weather activity can occur at any time during the solar cycle.

We hope that this information will help dispell the popular myth that geomagnetic and auroral storm activity on the Earth will stop now that we have passed the solar maximum. This couldn’t be further from the truth. Statistically, the declining years of the solar cycle are the most stormy in terms of geomagnetic and auroral activity.’

    It’s rather rare to see it from Victoria especially as bright as this one was. We’re at solar minimum in the sun spot frequency cycle at the moment but large eruptions can occurr at any part of the cycle. There was a good one last year but I missed it. Sometimes it’s been seen as far north as outback Queensland border – away from city lights.

    Nice one, Ern. I photographed a fair few aurorae from central Scotland over the years, and was in the habit of always checking the sky each night, just in case something was happening. When I first arrived Down Under in Feb 86, I couldn’t sleep, partly because of the heat, and partly because of jet-lag. I lay on the floor in front of a fan, thinking ‘I should check the sky,’ but couldn’t be bothered. That night there was a rare blazing red aurora (at solar minimum), and a friend nearby thought ‘I should call Duncan, but he’s probably tired from jet lag’ :-( I saw the pic on the cover of the local paper later on.

    I’ll see if I’ve got any aurora pics handy.
