Vortex in the Sky

The night of May 11, 2024 was one for the books. One of the strongest train of Coronal Mass Ejection (CME) events hit the magnetosphere of the Earth, repeatedly plucking the planet's magnetic field like guitar strings. This resulting release of energy led to one of the strongest and longest shows, with the aurora visible all the way down to the low latitudes.

Out in the Pacific Northwest, we were blessed to have it coincide with excellent viewing conditions. As dusk turned to twilight, the anticipation in the crowd gathered around grew. Soon, the faint glow became visible above us, a green band extending east to west. The glow was still dim thanks to the moonlight. But once the moon set, the substorms started hitting, and all the graphs started spiking. And the sky glowed with the brilliance of the lights.

Curtains of light twirled above the horizon. But up above, the aurora danced like a vortex of celestial energy, ribbons of light unfurling in the cold night sky. The ribbons pulsed and weaved, forming and reforming a thousand different shapes with every sub-storm that day

I will never forget the exhilaration I felt in that moment. I hope these memories will last a lifetime.

Light of the night

The mother of all solar storms slammed the planet on May 9th. I even briefly observed the Kp scale going down to an unheard level of Kp9. The strength of the storm was 4x of the typical that I had witness in the PNW in the past. And it wasn't just one event, it was a train of half a dozen storms that impinged the planet in that timeframe. And during the height of these impacts, the auroral displays were observed as far south as Mexico, Austria and India, and as far north as Australia.

The internet has been flooded with plenty of images of this event over the past few days. Here is my contribution to this, an example of how the faint glow in the sky was really a dazzling spectrum of colors that arced all over.
