Abstract

Super magnetic storm occurred on October 10, 2024, and a super substorm occurred at the beginning of the storm just after the shock arrival at 1520 UT. As a result, red aurora were photographed at multiple points over wide region of Japan from 1700 UT. A new Bayesian analysis enables us to estimate the time variation of the most probable height and latitude of the red aurora based on the citizen science dataset in combination of POES/MetOp satellite datasets of electron precipitation boundary. We found that the top height of red aurora extended to ~850 km and the red aurora shifted toward low latitude according to the storm development. The ultra-high altitude of the red aurora can be evidence of rapid atmospheric heating and the atmospheric expansion.
