[Nick James]

I've put an animation of two 30x60s stacks on the web here:

See if you can spot the two fragments!

> designated P/2015 Y2 but was soon linked to P/2010 V1 with a perihelion
> 7.2 days later than expected. CFHT images show a second object 92" E,
> 44" S of the main fragment. It is probable that the comet fragmented at
> the 2010 return following an outburst.
