COMETS COMETS
DEEP SKY DEEP SKY
A 19th magnitude comet was discovered in PanSTARRS 1 images taken with the 1.8m Ritchey- Chretien on 2014 November 26. Tim Spahr identified pre-discovery observations in images taken by Mt Lemmon, ISON and Catalina. The comet will reach perihelion at 3.4 au in 2015 June and has a period of around 30 years. An encounter with Saturn will increase the perihelion distance to 3.7 au and slightly reduce the period at the next return.
