Here are instructions how I added the comet to Guide 9.1

You find the orbital elements on this website:
Search for "Orbital Elements" on that page and use the first block of
elements (for Epoch 2019 Dec. 23.0)

Now in Guide click on Extras / Asteroid_Comet_Options /
Edit_Comet_Asteroid_Data / new_Comet
and enter these data:
Name: use whatever you want
Date of Perihelion:  use the "Epoch" data, but in different order:
9.42985 Dec 2019
Perihelion Distance: use the "q" value
Eccentricity: use the "e" value
Argument of perihelion: use the "Peri." value
Long. of ascending node: use the "Node" value
Inclination: use the "Incl." value
For Absolute Magnitude use 10, I did find this value by try and error.
Slope parameter: I don't know what it is, leave it at 5.

Then the comet will be visible in Guide. Don't forget to set the comet
brightness in Display / Data_shown to a big enough value, or use "on".

If anyone knows how to automatize this process, please let us know.
