Bright Comets

This page provides constantly updated information about bright and interesting comets. Bright comets that are currently visible and for which recent observations are available from the Comet Observation database (COBS) are listed first, in order of decreasing brightness. When recent observations are not available, the magnitude provided by the JPL Horizons datasets is shown. This list includes 220 comets.

Visibility from selected location
visibility = visible to the naked eye
stars = binocular, brighter than 10th magnitude
= current altitude ≥ 30°   = current altitude < 30°   = below the horizon
