About NGC 5024

NGC 5024 (M53) is catalogued as a globular cluster in Coma Berenices. Its J2000 position is RA 13:12:55.23, Dec +18:10:08.8, corresponding to 198.2302 degrees RA and 18.1682 degrees Dec. The local catalogue places it about 56,400 light-years away. Its referenced angular extent is approximately 12.6 by 12.6 arcminutes.

Observing tips

StarWatchr rates this as an easy target at magnitude 7.6. It is associated with spring observing, with midnight placement typically strongest around April. From 52 degrees north its theoretical meridian altitude is about 56.2 degrees; local horizons and the live altitude chart determine the practical window.

A small telescope under reasonably dark skies is a good starting point; use the live altitude chart to choose its highest point.

What to expect

The SIMBAD classification for the matched source is GlC. A published radial velocity value is -63.1 km/s. The SIMBAD record currently connects it to 917 bibliographic references.

At roughly 12.6 arcminutes across, it benefits from a narrower field and adequate image scale. Use the listed 12.6 by 12.6 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
