Sprite Halo
This was a very prolific session, concerning TLEs. More than 120 events were observed during the evening of Nov. 11, 2023 over #thunderstorms at E. Aegean Sea and W. Turkey. This is a halo event (the red "disk") accompanied by red sprites below.
TLEs (like red sprites) are upper atmospheric electrical discharges and they appear, under specific circumstances, above thunderstorms (e.g. red sprites appear at altitudes of 40-90 km).
I've used a #Sigma 85 mm lens at f/1.4, for 1/25'' with 40 k iso.
Check our recent #paper about TLEs from Greek-based observers, here: doi.org/10.3390/environsciproc2023026009.
