NOAA 30 min forecast

UPDATE Friday: –– For readers in darkness, there is currently a G4 geomagnetic storm. Satellites at L1 suggest a spike in density (SWEPAM) coming through in minutes (5.30pm WST 8.30pm EDT). See Glendale for live reports of where the action is. Graphs and discussion at SpaceWeatherlive. Nullschool-Space (a very low resolution, generic estimate) is as colorful as it gets.

Did a short sharp Geomagnetic storm contribute to the Callide Coal plant explosion?

Ben Davidson speaks from Spaceweathernews.com and claims that there was a short sharp geomagnetic storm over the East Coast of Australia around the time the Queensland Callide Power plant exploded.

The CME that flew past Earth didn’t do much around the world, causing a small 1% deviation in magnetometers. But there was a burst of activity in the Southern Hemisphere that appears to have hit the east coast of Australia. Magnetometers there saw a 300 – 500% change* between noon and 3pm on the same day as the Callide Coal Power Plant blew up. The explosion happened at 1.44pm and the 275 kV transmission lines tripped at 2:06pm.

*(UPDATE: There is some contention in comments about the Australian DST figures — we’re they really that high or unusual? I’ll update the post when I can confirm it either way).

We don’t know if this tipped something over the edge at Callide, but the timing is highly coincidental. If Earth’s magnetic field is weakening it would seem urgent, to say the least, to understand the risks these spaceweather events pose to our critical infrastructure.

Perhaps an engineer who knows the design of (hydrogen cooled) supercritical coal reactors might be able […]
