Are red sprites of solar origin?
Probably yes! The direction of their velocity is from above to below. They form branches as solar prominences. More sprites can have a common dark level in the ionosphere – similar to missing sections of prominences. The velocity of the flight of the red sprites downwards is 10 000 km/s. Also the biggest lightnings have the velocity of only some hundred km/s. Solar storms have a velocity of this order (Fig.1). The hit cloud emits gamma rays. Only solar processes can do this, no processes in the terrestrial ionosphere. The hit air probably emits ultraviolet light which can be observed together with the auroras. Lightnings come from the bottom of a cloud, the gamma rays from the top of it where red sprites hit. The solar influence on our climate is proved. But this influence is probably not only the result of the cosmic ray particles which produce many secondary particles but not enough to create big clouds. Moreover, the path of these seeds remains very small, some meters in diameter wh
