COMETS COMETS
DEEP SKY DEEP SKY
A 19th magnitude comet was discovered in PanSTARRS 1 images taken with the 1.8m Ritchey- Chretien on November 17. Tim Spahr identified pre-discovery images of the comet in Catalina Sky Survey data from October 26 and November 16. Calculations by Hirohisa Sato suggest that it moves in a long period ellipse.  It will be near 12th magnitude and at its brightest, though it will remain near this brightness for a while.
