Super thunder above Athens, captured from my home at Chalandri. Note the direction of the thunder streams. Some fall behind Imitos mountain while other start from the clouds and return to the clouds forming some loops. At least two of them seem to span from the south to the extreme north regions of the city covering horizontally a distance of approximately 20 kilometers.
