In this day it was a bit hazy so I couldn't detect an ion tail captured on Nov 9. You can see only very distributed dust tail in western direction in this image. I have estimated the comet has a brightness of brighter than 8th magnitude. We can observe the comet almost all night in lower southern skies in November.
