Resumo

Based on the results of the imaging photometer at the Verkhnetulomsky observatory measurements, 61 series of UV-microbursts were recorded over two seasons — non-periodic successive short UV-emission pulses (less than 500 ms each), lasting from tens of seconds to hours. A study of the spatial structure of UV-microbursts was carried out using the example of the event of November 21, 2021. It is shown that one series can represent an alternation of spots, arcs and diffuse glow outside the field of view. The characteristic sizes of the glow areas are determined.
