Footnotes:

The site uses Minor Planet Ephemeris Service to generate perturbed ephemerides for comets.
Comet magnitudes are calculated based on derived magnitude parameters from the latest available observations in the COBS database.

Terminology:

RA right ascension in hours
Dec declination in degrees
Delta distance between comet and Earth (AU)
r distance between comet and Sun (AU)
El elongation - the angle between the Sun and comet
Ph percent of surface illuminated
Mag magnitude - brightness estimate
