Earlier this year I wrote about the sun's multiple solar flares (coronal mass ejections, or CMEs) and the resulting aurora borealis illuminating the night sky over the northern hemisphere. Sadly at that time, cloud cover in the area prevented me from viewing them. Until now.
Above our heads was this vision - an angel? A dove? What do you see? This type of Northern Light is called a 'Divergent Coronal Aurora.' |
My partner and I are avid sky watchers and when we read that a Category 4 CME (Category one being minor, five major) was on its way to earth, we prepared ourselves for an art in the sky event. Coats? Check. Touque? Check. Portable chairs? Check. Wine? Absolutely check.
Scientists have determined that solar flares from our sun have an eleven year cycle. This year, 2024, is the final year of the solar cycle and, as is typical for the cycle's end, the blasts occur more frequently and with more strength. The result? The most beautiful art-in-the-dark-sky you have ever seen.

Solar flares (CMEs) occur when a powerful geomagnetic solar storm takes place on the sun's surface, causing a burst or multiple bursts of energy. These energy bursts erupt into a coronal mass ejection (CME) which launches billions of tons of plasma into space. The plasma travels at an incredible solar wind speed of 750-800 km per second (470-500 miles per second). The magnetized plasma particles will take a couple of days to reach our planet and when they arrive, the earth's own magnetic field prevents it from reaching us directly. Instead, the active plasma is dispersed across the magnetosphere, resulting in the famed aurora borealis. The magnetized plasma will, however, have the capability of disrupting hydro grids, causing radio/GPS black-outs and degrading satellite reception. High-altitude planes will lower their flight path in order to avoid exposure to any radiation leaking through the magnetosphere.

ReplyDeleteGorgeous pictures. Thanks for sharing.
ReplyDeleteThanks Vijaya. In all my years of sky-watching, I've never seen anything like it 😯
