Bright Comets
This page provides a comprehensive list of the bright comets currently visible in the sky. This list is updated
with new information several times per day.
Comets for which there is data from recent observations reported in the Comet Observation database (COBS)
are listed first, in order of decreasing brightness.
When data from recent observations is not available,
the magnitude provided by the JPL Horizons datasets is used
as an estimation of the brightness.
