Today's highlights

• It's tricky to predict, but newly discovered comet C/2023 A3 (Tsuchinshan-ATLAS) is a truly promising one for autumn next year. Here you can find detailed information, a 3d orbit visualization, interactive star maps and a real time position tracker to start following and observing it.
• Tonight observing guide from Greenwich, United Kingdom [change]
• The Sun is in the constellation of Pisces. The Moon is in the constellation of Aquarius and it is in Waning Crescent (Approaching New Moon) phase.
• Comet ZTF (C/2020 V2) is in the constellation of Triangulum and its latest estimated magnitude is 11.96. It should be visible with the help of a telescope havng an aperture of 8 inches (200mm) or more.
• Comet C/2022 E3 (ZTF) is in the constellation of Eridanus and its latest estimated magnitude is 12.13. It should be visible with the help of a telescope havng an aperture of 8 inches (200mm) or more.
• Comet C/2017 K2 (PANSTARRS) is in the constellation of Horologium and its latest estimated magnitude is 12.47. It should be visible with the help of a telescope havng an aperture of 8 inches (200mm) or more.
• The next close approach with a Near Earth Object (NEO) will happen with Asteroid (NEO) 2023 FG on Mar 23 2023 at 04:45 UTC (2 days 18 hours 21 minutes), at an approach distance of 682,636 kilometers, or 1.78 lunar distances, and a relative speed of 10.78 kilometers per second.

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.
