Auroral corona - Kirkjubæjarklaustur, SE Iceland

This image is taken looking almost at the zenith which is located close to the centre of the upper edge of the frame.

On March 24 2023 the aurora became particularly intense after 1.00am.
What was truly astonishing is that at a certain time the aurora appeared to emanate explosively from a point directly overhead, not unlike a firework going off.
The aurora spread out rapidly over the course of less than a minute or so forming dome like structures overhead, filling one's entire field of view, with alternating concentric green and pinkish red banding. The banding and the dome like structure diffused away over several more minutes.

I learned subsequently that I had witnessed what is often referred to as an auroral corona (crown). Luckily I was running a time lapse sequence on my camera pointing roughly at the zenith. The rest of my party slept through the show.........

Canon 800Da, Sigma 18-35 mm Art at f1.8 and 18mm, ISO 1600, 2s (the previous frames to this one burned holes in the sensor!)

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
