2023 September 19 (local Melbourne time)

On September 16 (UTC), a magnetic filament erupted from the Sun creating an Earth-directed full halo CME that sparked G3 geomagnetic storm conditions in the pre morning-twilight hours of September 19 Melbourne time. The storm persisted during Melbourne's daytime and G2-class conditions continued, but by the time evening twilight had started to fade geomagnetic conditions had weakened considerably.

From Tooradin, no auroral activity was visible to the naked eye or on frames viewed on the camera's screen. Only during upload and viewing on my home computer's monitor were faint auroral structures noted. It was decided to head home, somewhat disappointed, when light clouds started to roll in just after 8 pm.

Here's three for the record.
