The global atmospheric electric current (GEC) as a system is generated by the charge distributing processes during thunderstorms. We discuss atmospheric electro-optical phenomena as an integrated part the GEC, focusing on intense discharges during thunderstorms, resulting in transient luminous events (TLE) between the cloud top and the lower ionosphere. Red sprites are the most commonly observed group of TLEs; they occur following intense tropospheric lightning discharges that cause a transient quasi-static electric feld stretching between the clouds and the ionosphere. At a critical strength of the feld, a streamer starts and propagates downwards, free electrons excite N2 molecules leading to red light emissions. We discuss the forming and morphological properties of sprite events and diferent means of capturing them. In the second part, we introduce the UHU proposal, which is a possible experiment hoped to be conducted by the astronaut of the HUNOR mission (Hungarian to Orbit – Hungary’s ongoing mission to send a man to the International Space Station). UHU aims to collect images of TLEs from space, paired with extensive observations from the surface, in the hope of capturing the same event both from the Earth’s surface and from orbit, a result that has never been achieved before.
