Variation of JSR is, therefore, an important probe to investigate generation and dissipation processes of the relativistic electrons and deformation of their global distribution. Regular and systematic JSR observations have been made by several groups and revealed the existence of short term variations at a time scale of several days to months inferring some electro-magnetic activities in the inner magnetosphere. Now it\u0027s the time to investigate the details of variation characteristics and origin of the time variation. A program of a multi-frequency observation for JSR has been started since 2001. The JSR spectrum measurements give us information of variations of pitch angle and/or characteristics of radial diffusion of the relativistic electrons. In this program three observation frequencies measured with different facilities have been adopted; i.e., 325 MHz at Tohoku Univ., 930 MHz at European Incoherent Scatter Facility (EISCAT), Sweden and 2.22 GHz at National Institute of Information and Communications Technology (NiCT). JSR at the frequency range is generated from the relativistic electrons at the energy from 6 to 16 MeV, and has been hardly observed regularly. We have made approximately two week observation in October 2003 and one month observation in June to July 2004. A preliminary analysis shows existence of radio flux variations.

内容記述 | Jupiter's Synchrotron Radiation (JSR) is generated by the relativistic electrons trapped in the radiation belt. Variation of JSR is, therefore, an important probe to investigate generation and dissipation processes of the relativistic electrons and deformation of their global distribution. Regular and systematic JSR observations have been made by several groups and revealed the existence of short term variations at a time scale of several days to months inferring some electro-magnetic activities in the inner magnetosphere. Now it's the time to investigate the details of variation characteristics and origin of the time variation. A program of a multi-frequency observation for JSR has been started since 2001. The JSR spectrum measurements give us information of variations of pitch angle and/or characteristics of radial diffusion of the relativistic electrons. In this program three observation frequencies measured with different facilities have been adopted; i.e., 325 MHz at Tohoku Univ., 930 MHz at European Incoherent Scatter Facility (EISCAT), Sweden and 2.22 GHz at National Institute of Information and Communications Technology (NiCT). JSR at the frequency range is generated from the relativistic electrons at the energy from 6 to 16 MeV, and has been hardly observed regularly. We have made approximately two week observation in October 2003 and one month observation in June to July 2004. A preliminary analysis shows existence of radio flux variations. In particular, the variation showed frequency dependent and rapid decreasing feature in October 2003, which infers that new ideas of energy loss process are required in the dynamics of low energy radiation belt electrons. | |||||
