[BAA Comets] Recovery of P/2010 V1 (Ikeya-Murakami)

[Shanklin, Jonathan D.]

Quoting from my predictions for 2016:  2010 V1 was discovered in outburst, and its magnitude at this return is uncertain.

It seemed unlikely that it would be as bright as at discovery.  However, it may fragment again, so do keep on observing!

This comet, which was discovered in 2010, was predicted to reach 10th magnitude around now but, until yesterday, there was no sign of it.

CBET 4230 reports that the comet has finally been recovered by PanSTARRS on December 31 at around mag 20.8. The new object was originally 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.

I managed to get an image of both components from Chelmsford tonight:

They are very faint but both move in the correct direction relative to the stars when I blink the stacks. The main component is around mag 19 in R. These are probably some of the faintest cometary objects that I have ever observed from Chelmsford.

Nick.
