[PPS01-P10] Identification of Jupiter's hectometric radiation associated with reconnection in the magnetotail
Keywords:Jupiter, hectometric radiation, reconnection
We have reanalyzed occurrence characteristics of HOM using the WIND data to investigate precise relation between occurrence of nsw-HOM and Jupiter's magnetospheric variations observed by the Galileo Jupiter orbiter. As a result, we found that HOM has the 3rd nsw-HOM component appearing from 340deg to +20deg in CML which generally appears quasi periodically with the time scale of a few to several days and also shows long-term occurrence variations with seemingly capricious time scales. A comparison study between the occurrence timing of the 3rd nsw-HOM and magnetospheric events for the Galileo era indicates that most of the 3rd nsw-HOM appeared when magnetic reconfiguration events occurred in the magnetotail region. We show the precise occurrence features of the 3rd nsw-HOM and discuss their possible source locations based on a comparison study with Jupiter's UV auroral images.
