If seeing the aurora australis was on your bucket list this year, tonight might be the night.
A G2 (or moderate) geomagnetic storm is expected to reach Earth on Friday August 28, creating the conditions for the southern lights to become visible across parts of southern Australia and New Zealand.
Here's what you need to know about a possible aurora australis – and when to look up.
When could you see the aurora australis?
For those hoping to catch a glimpse, the current forecast points to 60 to 75 minutes after sunset on Friday, August 28, local time.
Based on this timing, approximate local viewing times across Ausrtalia are as follows:
- Sydney: 6:34–6:49pm
- Melbourne: 6:55–7:10pm
- Canberra: 6:41–6:56pm
- Hobart: 6:40–6:55pm
- Adelaide: 6:54–7:09pm
- Perth: 6:57–7:12pm
- Auckland: 6:57–7:12pm
- Wellington: 6:52–7:07pm
- Christchurch: 6:58–7:13pm
- Dunedin: 7:03–7:18pm
Keep in mind, auroras are notoriously difficult to predict. The strength and timing of the incoming solar activity can change, so it’s worth checking the latest space-weather and aurora forecasts before heading outside.
Where in Australia could you see it?
The further south you are, the better your chances. Tasmania, Victoria and southern parts of South Australia and Western Australia should get a glimpse, particularly from locations away from city lights with an unobstructed view towards the southern horizon.
The full moon will complicate viewing conditions
Unfortunately for us, the Full Moon will make tonight's viewing conditions trickier.
The extra light in the sky can wash out a faint aurora, making it harder to see with the naked eye and more challenging to photograph. If you're heading out, find somewhere as dark as possible and give your eyes time to adjust.
Your phone may also have a better chance of picking up faint auroral colours than your eyes can. A night mode or long-exposure setting can help capture activity that looks much more subtle in person.
