Red Sprite behind the castle of Beynac

Mystical and unreal atmosphere at the Château de Beynac 😍

The appearance of this magnificent "sprite" on the night of September 3 to 4, 2022 will remain in my memory. When it flashed on the 4K video screen, I almost missed the record button so much it surprised me... 😅
It was a powerful lightning at about 315 km near Valence in the east of France that caused this transient luminous event to appear in the upper atmosphere (between 50 and 90 km altitude). You can even see the flash on the horizon.
The camera sony A7s being modified "fullspectrum", we can see some strange colours related to infrared in the bottom of the image (grey tints)

This same sprite was also taken with a longer focal length (105mm). The resolution of the image is then much better but there is no longer the pretty landscape...

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.
