Astronomers observe outburst of comet 15P/Finlay

(Phys.org)--A Jupiter-family comet, designated 15P/Finlay, has experienced two large-scale outbursts during its perihelion passage at the end of 2014 and the start of 2015. The latter was observed by a team of astronomers, led by Masateru Ishiguro of the Seoul National University in South Korea, offering a rare glimpse into the physical properties of cometary nuclei. The results of these observations are published Sept. 3 on the arXiv pre-print server.
