The attached V-band image was taken this at 1929 UTC on October 5 using
the Alnitak CDK 17 in Spain as part of the BAA time allocation.

I get a magnitude of 11.6 using comphot. The characteristic shape of the
expanding coma from last time is visible again. This time the teardrop
is extended to the east with a dark lane becoming apparent in PA 80 deg.
