Why it matters here
The watch day of 11 October in UTC runs from 11am Sunday to 11am Monday on the Mid North Coast, so Sunday night is our window. Auroras show far less often this far north than in Tasmania or Victoria, so treat any glow low on a dark southern horizon as a bonus.
Well, petal, two clouds off the Sun catching each other up on the way here is a lovely thing to picture. If Sunday night's clear, find a spot away from the streetlights with a view south, take a thermos, and knock on the neighbour's door on your way, because a sky show is better shared. And if all we get is stars, that's still a good night out. Do you ever wonder how many of these storms pass right over us without anyone looking up, petal?
