AB: ISUAL, the scientific payload of FORMOSAT-2 satellite, recorded approximately 2,000 transient luminous events (TLEs) in the first 1.5 years of operation after launch. By geolocating the ISUAL registered events using the spacecraft position and attitude data, the global distribution and seasonal distribution variation of the TLE events can be obtained. Several hot zones of high TLE appearance rate are identified, including South China Sea, central Africa, Caribbean Sea and central Pacific Ocean. The first three hot zones were reported by previous lightning or ELF surveys, but the last one, central Pacific Ocean, was not noted before. Our results show the ocean vs land occurrence rates for sprites and elves are quite different. Elves preferentially occur above ocean, whereas sprites tend to be triggered by lightning over the land. A more indepth comparison with results from other global surveys will also be reported.
