The time variable phenomena of Jovian decimetric radiation (DIM) are expected to have relation to little known dynamic process of Jupiter's inner magnetosphere. A program of regular DIM observations has been started since 1995 to reveal characteristics of DIM flux variations especially on a time scale of days to months, which must be deeply related to Jupiter's global electromagnetic activities and/or solar activities. A daily monitor of DIM has been made at a frequency of 327MHz with the 2000m 2 radio telescopes. The radio flux variations on a time scale of approximately 10 days were detected for the period from the end of August to September, 1995, around the middle of May and from the end of June to July, 1997. The flux variations were nearly 40% and 25% for the 1995 and 1997 observations, respectively.
