Last night, the entire world knew something was up. They were seeing the aurora in Ireland, in the UK, there were fantastic shows above Tromsø, in eastern Canada the aurora was in the skies, even in the northern US. But what I personally didn't know, despite various internet reports and infamously oversaturated photos of the northern lights on Pinterest, is that there were orange auroras - really, really visible to the eye. It was spectacular, and it was all thanks for a high speed solar wind stream buffeting Earth's magnetic field at some 776 kilometres per second. What a month October is shaping up to be already!
