After treating skygazers across Australia to a stunning celestial light show in May this year, the Bureau of Meteorology predicts the aurora australis could return tonight due to significant geomagnetic activity, including as far north as parts of NSW and South Australia. This would no doubt be welcome news for Sydneysiders and NSW residents who missed out on the previous technicolour display due to bad weather.
The BoM released an aurora watch notice early this week predicting significant geomagnetic activity that could trigger dazzling auroras late at night. The storm is expected to be the strongest tonight, Tuesday, July 30. Here’s everything you need to know.
What is causing the Auroras?
According to the BoM, the celestial display of red, pink, and green is caused by “solar wind” or large expulsions of plasma that travel from the sun toward the Earth at high speeds of up to 2000km per second. The auroras are caused when these particles collide with the gases in the Earth’s atmosphere triggering a colourful display.
When can you see it in Australia?
The aurora is most visible in high-altitude places. Tasmania, southern parts of Victoria and Western Australia could be treated to the most striking display but if the storm ends up being as strong as predicted, it could be visible in South Australia and parts of NSW.
How can you see the aurora australis?
Keep a close watch on weather forecasts and local community groups if you’re planning to head out. You don’t need any special equipment to see the Aurora in either hemisphere.
Where could you spot it in NSW?
Although it’s hard to predict exactly where the aurora australis could be seen especially here in NSW, multiple spots like Wollongong and some parts in the Illawarra region were treated to the display in May. Dark sky spots without any light pollution could also be a safe bet. See the full list of places here and good luck!
