Near-UV Pulsations in the Aurora Region Measured by Orbital Telescope TUS during High-Intensity and Long-Duration Continuous AE Activity

Tracking Ultraviolet Set-up (TUS) on board the Lomonosov satellite measured UV intensity pulsations in auroral region. Sixty-four events with were registered during two measurement periods from 26 December 2016–10 January 2017 and 8–15 November 2017. During both periods, a high-intensity, long-duration, continuous activity (HILDCAA) was detected. Simultaneous measurements LEO by (DEPRON detector) Meteor-M2 satellites show enhanced fluxes of trapped precipitated energetic electrons region Earth’s outer radiation belt these periods. We found that most UV-events correspond to electron (E > 100 keV) precipitation. One can suggest particles higher energies cause pulsating emission relatively deep atmosphere.
