Jellyfish Sprite II
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. Some clouds can also be seen at the bottom end, where the tendrils are. 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.
