[BAA Comets] Post-perihelion fragmentation of 168P/Hergenrother

[Richard Miles]

Thanks Nick for capturing such a good image with the Moon so bright and 
close.

There does appear to be a finger projection / bifurcation in the near-tail 
around 4 arcsec and p.a. 150 deg from the brightest pixel position.  This 
might be the remnant part of which has formed a slight tail of its own. 
Certainly shows that we still have only the one comet nucleus persisting.

Maybe needs a 2.0-m scope, smaller FWHM and dark sky to see what's going on.

Richard
