Abstract

The detailed observation of Jovian decimetric radiation (DIM) from relativistic electrons in the Jovian radiation belt has been carried out to seek the existence of its short term variation. In the observation, the terrestrial atmospheric extinction effect was corrected using the sky tipping method. Moreover, the back ground confusion which was the serious problem of the past observations was also evaluated. As the result, the DIM flux enhancement with a duration of a few days in November 1996 was confirmed. The data also showed the changes of the magnetic latitude beaming curves during the flux enhancement. These results showed that the relativistic electrons in Jovian radiation belt which has been thought to be stable has a short term variation.
