Aurora Australis (Southern Lights) Forecast for Thursday, December 12, 2024
Latest Forecast = in 12 minutes, the Aurora will be Quiet
When and Where are the Southern Lights tonight in Australia and New Zealand?
Here's Everything You Need to know. . .
By JIM THOMAS -- Soft Serve News
The Aurora Australis, like its northern cousin, is difficult to predict with precision. It has stops and starts (known as sub-storms). Patience is important, but so is information. Here are some tools that will increase your chances of seeing it.
REAL TIME AURORA AUSTRALIS PREDICTION:
Here is the prediction of storm intensity for the next few minutes (the higher the Kp number, the larger the Aurora):
in 1 minutes, the Geomagnetic Activity level (Kp number) will be 1.67 -- Quiet
in 5 minutes, the Geomagnetic Activity level (Kp number) will be 1.67 -- Quiet
in 8 minutes, the Geomagnetic Activity level (Kp number) will be 2 -- Quiet
in 12 minutes, the Geomagnetic Activity level (Kp number) will be 2 -- Quiet

Now, find the Kp number line on the following map that matches the Kp number predicted above. If you are located at or below the estimated Kp line, you are in the right spot. You might even be in luck if you are located within next higher line, but you will have to look lower on the horizon. Be aware though, ground based light pollution and weather will have a greater impact at these more marginal locations.

EARTH LIGHT & MOONLIGHT POLLUTION:
Dark. Dark. Dark. It is not just about low light. It is important to remember the widest part of the Aurora is when the sun is on the opposite side of the earth. So late, nighttime (or early morning) dark tends to be best. But you also want few competing light sources so get away from the city lights and let your eyes adjust to the darkness. The further away from those earth based light sources the better for seeing the Southern Lights. Full moons hurt a bit because they increase ambient light and darkness is best for viewing. The darker the moon, the better. Here's how the moon looks right now:
YOUR LOCAL WEATHER:
Auroras happen in the upper atmosphere, so if there is cloud cover, you are out of luck. Cold and clear are best for viewing the Aurora.
LOCATION:
Realistically south is where you need to be. The stronger the Aurora Australis, the more north one can see it. Check the Kp maps (above) and the size of the aurora oval (also above). Also, if you're not sure which way is south, don't forget to bring a compass.
THE PROBLEM WITH SEEING THE AURORA:
Let's say two months from now the Aurora is flaring up in your area -- the sky is ablaze with greens, violets and reds -- but instead of watching it, you're home sitting on the couch.
Why? Because you simply didn't know about it.
That's one of the problems with seeing the Aurora. It doesn’t run on a schedule. Often Auroras happen with only 30 minutes warning.
That's why it's important to have a partner watching out for it for you. Someone who will watch the Aurora data, then, notify you immediately when the conditions are right for your area.

REAL TIME AURORA FORECAST MAP
It's helpful to get confirmation of activity with NOAA's Ovation map. The Kp number gives nice info on how large the storm is, but the Ovation map does a better job of telling you if you can actually see it. It gives a 20 to 40 minute forecast of the predicted size of the aurora along with a color-coded probability of seeing the aurora over various spots on the Earth. Here is the most up-to-date image:
It's a good sign if you see a thick aurora band with some areas of light yellow, orange or, better yet, RED on this map as opposed to just a thin (or transparent) band with only dark green.
The size of a visible Aurora will be bigger than what is shown on this map, because the map gives the overhead location of the Aurora. The area of a visible aurora is greater because it can be seen at spots other than 90 degrees directly up (straight above your head). The Aurora might be visible at 45 degrees, 30 degrees or even lower on the horizon depending on its brightness.
REAL TIME Bz
Bz is the solar wind's magnetic orientation in the up/down direction. Although an Aurora can happen with a positive Bz, a negative Bz is generally better. A negative Bz helps the solar wind grab the earth's magnetic field which can more easily lead to an Aurora. So a negative Bz is good. The more negative the better.
Each number in the diagram below represents a rolling 5 minute average of the Bz taken along the length of the solar wind stream. This data comes from a satellite about 1 million miles from earth. These 5 minute stream segments are all headed towards earth. They should arrive in 20 to 40 minutes. They are given in the order they'll hit earth, with the first 5 minute average hitting first. Think of each number representing a 5 minute long cloud of solar wind speeding towards earth. Remember, it's best for Bz to be negative, and the more negative, the better.
Inbound Bz averages. The number closest to earth will hit first.
