Following its discovery, the returns for 1916, 1923, and 1930 were predicted but on each occasion it was not recovered.
The 1937 return was recovered by Shin-ichi Shimizu (Simada, Japan) on January 31 after a calculation of the comet's orbit by Hidewo Hirose (Tokyo, Japan) after he took calculations for the 1923 return done by Alexander D. Dubiago and took into account perturbations from Jupiter.
All returns apart from 1957 and 1971 have been recovered.
Repeated close encounters with Jupiter have increased this comet's orbital period steadily since it was first discovered, it will likely increase again to 8.29 years when it next encounters Jupiter on December 2, 2018.
At some point between 2009 January 11 and 30 the comet underwent an outburst of around 3 magnitudes, brightening from 18th to 15th magnitude.
