“…3, where the locations of all known GJ events (red stars) are superimposed with the lightning distribution over the globe. Besides, black squares indicate some of eighty intense UV (300-400 nm) flashes, detected at ∼950 km onboard the student microsatellite 'Tatiana' (Garipov et al 2005). They were almost equally distributed between two groups with durations 1-4 ms and 10-64 ms, corresponding to the lifetimes of individual streamers and of leaders, respectively (see below).…”

Blue jets are beams of blue light propagating from the tops of active thunderclouds up to altitudes of ∼50 km. They resemble tall trees with quasi-vertical trunk and filamentary branches. Their apparent speeds are in the range of 10 s to 100 s km/s. Other events, having essentially lower terminal altitudes (<26 km), are named blue starters. These phenomena represent the first documented class of upward electrical discharges in the stratosphere. Some of upward discharges, termed gigantic jets, propagate into the lower ionosphere at much higher speeds in the final phase. We describe salient features of the upward discharges in the atmosphere, give an assessment of the theories of their development, and discuss the consequences for the electrodynamics and chemistry of the stratosphere. We argue that this upward lightning phenomenon can be understood in terms of the bidirectional leader, emerging from the anvil.

“…Besides ISUAL mission (2004-) (Chern et al, 2003;Mende et al, 2005;Su et al, 2005;Hsu et al, 2009) (Garipov et al, 2005;Garipov et al, 2006;Shneider & Milikh, 2010). With the Tatiana-1 data, Shneider and Milikh (2010) studied the atmospheric electricity phenomena that can serve as sources for short millisecond range flashes; they reported that the UV flashes in the millisecond scale detected by Tatiana-1 may have been generated by gigantic blue jets (GBJ).…”

Detectors on the "Universitetsky-Tatiana" satellite measured a smoothly varying intensity of UV radiation from the night-time atmosphere in the nadir direction and the intensity of the energetic electron flux at the orbit. At high latitudes the UV intensity in the auroral oval is interpreted as being due to electrons penetrating into the atmosphere. At middle latitudes the UV intensity is an order of magnitude less and more data are needed to reveal the origin of this radiation. Millisecond flashes of UV radiation were observed. The flashes' energy, temporal profile and global distribution are similar to these parameters for Transient Luminous Events (TLEs). These studies will be continued aboard the next satellite "Tatiana-2".
