Tonight's Observing Guide

Observing guide of astronomical events visible tonight from Greenwich, United Kingdom.

This page lists the Solar System objects visible tonight from Greenwich, United Kingdom following an ideal timeline that goes from today's sunset to tomorrow's sunrise. Only objects that will reach an altitude of at least 15° and set/rise at least 15 minutes after/before the Sun for given location are listed.

All rise and set times are expressed in local time (Europe/London) and are approximated with an error that could be as large as few minutes.

Tonight's Conjunctions

In astronomy a conjunction is defined as a close apparent alignment in the sky between two or more celestial bodies. Here we list, the closest conjunctions happening between objects we are currently tracking, in order of increasing separation.

The green arrow indicates that the objects are currently getting closer, while the red arrow means that the objects are increasing their apparent separation.
