System Feasibility of Transient Luminous Events Observation at the Summit of Mt. Fuji

Abstract

. We conducted a summer observation campaign of transient luminous events (TLEs) in 2019 at the summit of Mt. Fuji. A newly developed color full-HD remote camera system, monochrome charge-coupled device (CCD) cameras, and the receiver of very low frequency (VLF) band lightning detection system operated by Blitzortung.org were installed there. During the observation period, we obtained many events of the parent thunderstorm associated with lightning strikes identified by Blitzortung.org and the color optical flash image. Moreover, a sprite (one of TLEs) and the sprite-producing strike were detected by a monochrome CCD camera and Blitzortung lightning detection network, respectively. It was reasonable to estimate the location of lightning strikes in the Kanto area of Japan using Blitzortung.org. The results show that the observation system at the Mt. Fuji is feasible to promote the TLEs study.
