[BAA Comets] 46P/Wirtanen

[David Swan]

Hello,

It is good to see Martin Mobberley keeping us up to date with 46P while it is still at a very southerly declination.

I have been looking at the University of Maryland's 46P campaign page. There's quite a big difference between the fitted (and extrapolated) light curves generated from COBS observations versus MPC obs. Is this due to the former relating to total VEM and latter false nucleus mag? Or does this to some extent reflect very significant uncertainty on peak brightness around perihelion/perigee?
