...and right on cue on the www.ips.gov.au site:
"Outage due to power failure. Some datasets unavailable."

(relax - this was 6th August, well before the current CME - but it made me chuckle
before I noticed the date!)

The CME arrival is expected to be midnight tonight AEST. Auroras predicted to be
visible from Southern Australian regions - Crow Eaters and Taswegians lucky.
I was lucky enough to see an aurora (dark brown/purple) from suburbs of Adelaide when
I lived there in my youth. Back then we didn't have such good visibility that the
protons were incoming.
