Twilight Sprites
During the early morning on the 21st of Dec. 2024, several dozens of TLEs* were observed over thunderstorms at the Aegean Sea (northern as well as southeastern). This is a halo event (the faint red disk on top) with red sprites under it. One of the last events I managed to capture as the imminent sunrise was shedding light. The lights on the bottom left come from the islands of Andros, Tinos and Mykonos.
*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.
