Jellyfish Sprite
During the night on the 27th of Oct. 2025, 102 TLEs* were observed over #thunderstorms at NE. Aegean Sea, close to Lesvos isl. and NW Turkey. This is a so called "Jellyfish" red sprite event (a term used by sprite-chasers). That is, a group of "carrot" sprites stacked together, creating a red "dome" on top and a "forest" of tendrils at the bottom. My spot was at E. Attica, looking towards Evia's isl. mountains and NE Aegean Sea.
*TLEs (like red sprites) are upper atmospheric electrical discharges (cold plasma to be precise) and they appear, under specific circumstances, above thunderstorms (e.g. red sprites appear at altitudes of 40-90 km).
For this one, I've used a #Sigma 85 mm lens at f/1.4, for 1/25'' with 40 k iso.
