The observation was made by the Iitate Planetary Radio Telescope (IPRT) at Iitate Observatory in Japan during the period from October 16 to November 20 in 2003. Variations of the JSR intensity were compared with the solar F10.7 flux and it was found that the intensity of the JSR showed unusual increase of its magnitude by about 50 percent and the subsequent rapid decrease after the solar event with the decay rate of about 0.3 Jy/day. Comparing with the previous observations of the short term variation of the JSR, an unusual response of Jupiter's radiation belt associated with the rarely strong solar activity is supposed., 資料番号: AA0047898043}, pages = {167--170}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {The response of the Jovian synchrotron radiation at 325 MHz associated with the strong solar activity during October to November 2003}, year = {2004} }
