In the late evening, I had seen an Aurora alert published on social media. It said an Aurora was visible as far north and Adelaide and the Central Coast of NSW. So about 11:30 pm I went outside with my camera and tripod to see if it was visible in suburban Sydney.
The above photo is the best I could do in the time I had. There does seem to be a faint crimson glow on the lower left side (this is looking south). Photo details – 24 mm, f 1.4, 3.2 seconds, 1600 ISO. I later saw some quite good photos of the Aurora taken from the Central Coast of NSW in a much darker sky location – that showed it was indeed visible that far north.
