Blue jets



Blue jets

Blue jets are a second class of high altitude optical phenomenon and are distinct from sprites.

'Blues Jets' were observed for the first time in 1994. In fact, conical jets of blue light propagate electrically from the core and ejected from the top of the thunderstorms clouds towards the upper atmosphere at a speed of approximately 120 km/s. They usually propagate in narrow cones of 15 and do not exceed 40-50 kilometers in altitude. They are not directly related to cloud-to-ground lightnings and are not aligned with the local magnetic field.

Blue starters are brighter and shorter (reaching an altitude of only 20km).
