Bright Comets Today

These are the brightest comets currently visible in the sky. The Observed Magnitude and Coma Diameter values are derived from the Comet Observers Database by averaging the values reported in recent observations (more recent than 4 days), when available. The Estimated Magnitude comes from the JPL Horizons ephemeris service and might be inaccurate given the highly dynamic and unpredictable behavior of comets. When available please refer to the Observed Magnitude value and consider the Estimated Magnitude as a directional indication.

Active Meteor Showers Today

This is a list of the currently active meteor showers. The celestial coordinates refer to the meteor shower radiant position, i.e. the point in the sky where the meteors appear to come from. The ZHR value refers to the Zenithal Hourly Rate, i.e. the average number of meteors an individual observer could see in an hour, assuming perfectly dark sky conditions. This number is an estimate, the actual number an observer could see depends on the actual intensity of the shower (which can be highly variable) and on the actual sky conditions. Clicking on the blue square icon will bring you to a sky map showing the radiant position. The data used here is derived from Wikipedia.
