Those of you who caught the majest of the aurora: you have witnessed once in a century conditions. Last time we had this level of activity in one 24 hour period was in 1932.

In terms of absolute magnitude, we peaked at -412nT DST (essentially the level of “agitation” the magnetosphere has experienced), the greatest since the 1989 solar storms that took down the entire power grid of Quebec, which was on paper about 20% bigger but lasted for a shorter amount of time.

We had confirmed captures in Townsville and Florida – more than 7,000km from the geomagnetic poles. People captured it in most major cities on the planet, and saw it clearly in many others. Even Africa and South America didn’t miss out, which is unprecedented in modern times.
Happy Mother’s Day, you have witnessed something that statistically will not occur again in your lifetime.

Storm conditions are likely to stick for several days yet. They’re unlikely to reach this observed level again, but if you are in areas that saw it the last couple of days, be on the lookout. We will post forecasts near sunset if/when there’s some likely.
