The cache is a small camo container, hidden in the obvious spot.
Please replace the cache is such a way that no part of it is visible to any curious muggles.
Thankyou.
Click here and here to view a couple of rather spectacular video clips of Aurora Australis, also known as the Southern Lights. The aurora in the video was the result of a level G2 geomagnetic storm. The shooting location for the first one is Point Addis, adjacent to the Great Ocean Road overlooking Bass Strait, approximately 100km east of gz. The second one is taken from nearby Port Phillip.
What is the Aurora Australis?
Aurora Australis (also known as the Southern Lights, and the Southern Polar Lights) is the southern hemisphere counterpart to the Aurora Borealis, or the Northern Lights. In the sky, an Aurora Australis takes the shape of a curtain of light, or a sheet, or a diffuse glow; it most often is green, sometimes red, and occasionally other colors too. It is a natural phenomenon that causes spectacular colours to dance and shimmer across the night sky.
Like its northern sibling, the Aurora Australis is strongest in an oval centered on the south magnetic pole. This is because they are the result of collisions between energetic electrons (sometimes also protons) and atoms and molecules in the upper atmosphere … and the electrons get their high energies by being accelerated by solar wind magnetic fields and the Earth’s magnetic field (the motions are complicated, but essentially the electrons spiral around the Earth’s magnetic field lines and ‘touch down’ near to where those lines become vertical).
So by far the best place to see aurorae in the southern hemisphere is Antarctica, and obviously, at night! When the solar cycle is near its maximum, Aurora Australis are sometimes visible in New Zealand (especially the South Island), southern Australia (especially Tasmania), and southern Chile and Argentina (sometimes in South Africa too). On rare occasions, the lights can be seen further north with one even being visible just last week in the CO's home town of Mandurah, Western Australia.

About the colours: the physics is similar to what make a flame orange-yellow when salt is added to it (i.e. specific atomic transitions in sodium atoms); green and red come from atomic oxygen; nitrogen ions and molecules make some pinkish-reds and blue-violet; and so on.
How high are aurorae? Typically 100 to 300 km (this is where green is usually seen, with red at the top), but sometimes as high as 500 km, and as low as 80 km (this requires particularly energetic particles, to penetrate so deep; if you see purple, the aurora is likely to be this low).
It is also worth noting that the Aurora is best seen through a camera, with the colours being far more vivid that those seen by the naked eye. And if you happen to have the Northern Lights, Aurora Borealis on your wish list of places to see, then perhaps you might reconsider and plan on something a bit closer to home - our very own Southern Lights - Aurora Australis - which is no doubt every bit as spectacular, if you are in the right place at the right time.
Good luck with finding the cache!
