In KAGUYA (SELENE) LRS [1], WFC-L [2] observes waveforms of plasma waves in 100Hz-100kHz and a lot of electrostatic solitary waves (ESWs) have been observed. Some results were reported [3]. Although the orthogonal dipole antennas are generally used in the observations, sometimes a pair of monopole antennas were used. We analyze observations mainly by the latter antennas in the present study. Observed waveforms are fitted to ideal ESW waveforms. The waveforms observed by the monopole mode are susceptive to noises and generally they are not similar each other. Since the waveforms observed by the dipole mode are less affected by noises, we re-analyzed the data by fitting these waveforms to the ideal ESW waveforms. The observed ESWs have often components perpendicular to the background magnetic field. This means that the ESW potential structure has two dimensions and they are observed near the generation regions. The propagation velocity, the potential width, the potential depth, etc. of each ESW are also evaluated by comparing the waveforms observed by the monopole antennas. The data fitted to the dipole waveforms are used as references. Acknowledgments: The SELENE project has been organized by the Japan Aerospace Exploration Agency (JAXA).
