COBS lightcurve
A 19th magnitude comet was discovered in PanSTARRS 1 images taken with the
1.8m Ritchey-Chretien on 26 November 2014. Tim Spahr identified pre-discovery
observations in images taken by Mt Lemmon, ISON and Catalina. An encounter with
Saturn will increase the perihelion distance to 3.7 au and slightly reduce the period at
the next return.
