[BAA Comets] Observing alert: Next outburst of Comet 29P

[denis buczynski]

Hi Graham. 

I misread your email, I thought you were reffering to 29P but now realise that you were referring to 17P . 

There are BAA Comet Section images of 17P in the archive. These can be found at this link:

Observers may wish to try and detect the rotational lightcurve signature of the nucleus by means of inner coma photometry during the next few weeks whilst the coma is subdued.
