It’s very hard to predict when an aurora will arise mainly because it depends upon photo voltaic flares and wind from your sun! Even so, with longer nights in Wintertime, there’s much more opportunity to witness an aurora.
On the list of critical stargazing policies is to get no light air pollution to look at astral happenings, a thing New Zealand has in abundance.

The Aurora Borealis (Northern Lights) and Aurora Australis (Southern Lights) are the results of electrons colliding Along with the higher reaches of Earth’s ambiance. (Protons induce faint and diffuse aurora, normally not conveniently noticeable to the human eye.) The electrons are energized by acceleration procedures inside the downwind tail (night aspect) in the magnetosphere and at decrease altitudes alongside auroral field traces. The accelerated electrons follow the magnetic area of Earth all the way down to the Polar Regions the place they collide with oxygen and nitrogen atoms and molecules in Earth’s upper atmosphere.
When each of the circumstances are perfect, you could from time to time see the Aurora Australis without a camera. Generally it will eventually just be white vertical beams of sunshine, but if it is very highly effective you may be able to begin to see the colors While using the naked eye.
Except if you plan your journey and tours incredibly thoroughly upfront, or make connection with some area of interest aurora viewing teams, There exists a very good chance you'll be still left all by yourself to look for the elusive aurora australis.
Diffuse aurora surface somewhat structureless to an observer on the ground, with indistinct edges and amorphous sorts. Discrete aurora are structured into unique functions with nicely-defined edges which include arcs, rays and coronas; In addition they are typically Significantly brighter compared to the diffuse aurora.
The scientific phenomenon that triggers both auroras is exactly the same, irrespective of whether it is in the north pole or south pole.
Imagine it given that the Sunshine’s technique for sending out a little Strength and an entire large amount of billed particles in the universe.
This is why There exists a colour differential with Aurora Australis Photography Tips altitude; at superior altitudes oxygen purple dominates, then oxygen environmentally friendly and nitrogen blue/purple/crimson, then at last nitrogen blue/purple/purple when collisions reduce oxygen from emitting just about anything.
Warning: You're utilizing an previous Edition of Net Explorer which this chart no more supports. Be sure to update IE, or use A further modern browser. K-index data is loading.
Crimson: At its greatest altitudes, enthusiastic atomic oxygen emits at 630 nm (pink); small concentration of atoms and reduced sensitivity of eyes at this wavelength make this colour seen only underneath extra extreme solar action.
On the other hand, the depths of the Antarctic Winter season are definitely not hospitable to any traveller, with regular temperatures plummeting to negative 50 degrees Celsius, harrowing winds and dangerously icy disorders.
Numerous have viewed the Aurora Australis from Queenstown and Glenorchy, from areas with no mild pollution. You can't argue Along with the beautiful snowy mountains for a backdrop (based on the time not surprisingly).
