Comet Visibility Calendar
Bright comets are hard to predict. Most comets stay too faint to see without a telescope, and brightness forecasts often change as a comet nears the Sun.
How to find cometsUse a star chart app, look away from city lights, and start with binoculars.
When they are brightestUsually shortly before or after perihelion (closest approach to the Sun), low in the sky at dawn or dusk.
