The comet-Jupiter impact team of Beijing Astronomical Observatory has already reported that a strong Jovian decametric burst was detected during the period 0657-0707 UT on July 18. During the same period we also observed decametric radio bursts coming from Jupiter at Nishi-Harima Astronomical Observatory in Japan. The observations were made at 22.2 MHz with a phase-switched interferometer and a polarimeter, and also at 25.5 MHz with a radiometer. The radio bursts were polarized in the left-hand circular sense at 22.2 MHz, indicating that the radio source was presumably located in the southern polar region. The received power of the burst was of the order of that of the galactic background radiation.
