Not sure if anyone here has posted about this. Very significant:

JPL has the eccentricity around 3.5

Goes without saying, this is spectacular. This comet could do anything, probably worth keeping an eye on.

 

Cheers!

It's amazing how the planets and even the Oort cloud spiral around and follow the Sun through space at 490,000 mph.

Hello,

 

Does anyone have magnitude information on this comet? Also a sky chart so that non assisted visual observers could find it (if mag is large enough)?

 

All I could find was the heliocentric drawing, but no "day by day" sky chart position :-(

These seem to be projections from the website link provided. On Oct 11 still magnitude 16.9: Going to be a while till I start looking. I think they are still gathering data.

Mag 18 and heading our way out of Cassiopeia.  They are still trying to chart its path.

You can also use MPC to generate ephemeris
