Relationship between Radar Cross Section and Optical Magnitude based on Radar and Optical Simultaneous Observations of Faint Meteors
Ryou Ohsawa, Akira Hirota, Kohei Morita +40
Radar and optical simultaneous observations of meteors are important to understand the size distribution of the interplanetary dust. However, faint meteors detected by high power l…
A Fireball and Potentially Hazardous Binary Near-Earth Asteroid (164121) 2003 YT
Toshihiro Kasuga, Mikiya Sato, Masayoshi Ueda +3
We present a fireball detected in the night sky over Kyoto, Japan on UT 2017 April 28 at by the SonotaCo Network. The absolute visual magnitude is $M…
Near-Infrared Polarimetric Study of Near-Earth Object 252P/LINEAR: An Implication of Scattered Light from the Evolved Dust Particles
Y. G. Kwon, M. Ishiguro, J. Kwon +7
Aims. We aim to constrain the size and porosity of ejected dust particles from comet 252P/LINEAR and their evolution near the perihelion via near-infrared multiband polarimetry. A…
Optical and Near-Infrared Polarimetry of Non-Periodic Comet C/2013 US10 (Catalina)
Y. G. Kwon, M. Ishiguro, D. Kuroda +12
We present an optical and near-infrared (hereafter NIR) polarimetric study of a comet C/2013 US10 (Catalina) observed on UT 2015 December 17-18 at phase angles of =52.1 deg - 53…
OISTER Optical and Near-Infrared Monitoring Observations of a Peculiar Radio-Loud Active Galactic Nucleus SDSS J110006.07+442144.3
Tomoki Morokuma, Masaomi Tanaka, Yasuyuki T. Tanaka +80
We present monitoring campaign observations at optical and near-infrared (NIR) wavelengths for a radio-loud active galactic nucleus (AGN) at z=0.840, SDSS~J110006.07+442144.3 (here…
2014-2015 Multiple Outbursts of 15P/Finlay
Masateru Ishiguro, Daisuke Kuroda, Hidekazu Hanayama +21
Multiple outbursts of a Jupiter-family comet, 15P/Finlay, occurred from late 2014 to early 2015. We conducted an observation of the comet after the first outburst and subsequently…
