"G2 (Moderate) G3 (Strong) Geomagnetic Storm Watch for 01/02 Sep 2025" by NOAA Space Weather Prediction Center SWPC - Solar storm expected to peak Tuesday morning GMT (Monday night US/Canada West Coast) at G3 storm level. Kp=7 forecasts aurora in USA down to latitudes of Pennsylvania, Iowa and Oregon. If your weather is clear, find a viewing location away from city lights. Check updates at the time. spaceweather.gov/news/g2-moder #SpaceWeather #astronomy #aurora #AuroraBorealis #AuroraAustralis

I've finally gotten around to posting a blog about the Aurora Australis we had on the 1st of June this year.

I've included my camera set up and settings, and also didn't do any post-processing on my photos so you can see what comes out of the back of the camera.

Once again, the aurora numbers (Kp) crashed as the US West Coast got to astronomical twilight. Luckily, I hadn't started the drive out of the city lights. But if any of us decide to go out for an attempt to catch aurora, we have to take an attitude of accepting risk that it might not happen when we get to the viewing spot. spaceweather.gov/communities/a #SpaceWeather #aurora #NorthernLIghts #AuroraBorealis #AuroraAustralis #astronomy

A photograph of Sunday night's aurora from our backyard. It was about 7.15 pm.

Unfortunately our neighbour's security lights were shining, so the foreground is washed out because of it.

You can see the beams, and also it was the first time seeing a huge band of green above the main aurora. Usually if there is one it's red, but this time it was green.

Aurora Australis from Royal National Park! This is AMAZING.

The big solar storm that is passing us this week, triggered nu a coronal mass ejection from the Sun has produced a class G4 / G5 geomagnetic storm.

Our magnetosphere deflects most of the particles from Sun away, but near the poles, some spiral down and excite our atmosphere - producing aurora.

This storm was powerful enough to generate aurora sightings as far north as Coonabarabran and the Siding Spring Observatory. That's around 340 km NW of Sydney (closer to the equator, at 31 degrees south!)

While city lights drowned out the view for many, those under darker skies were treated to an extraordinary show. This stunning timelapse footage, captured by my friend Filippo Rivetti from Royal National Park south of Sydney, offers a glimpse of the awe-inspiring beauty and planetary-scale force of this event.

A reminder of the vast, dynamic forces at play: a star lashing out across space, and a planet, our home planet with its protective magnetic shield - hosting the only life we know of so far in the Universe, safely within.
