About NGC 6352

NGC 6352 (C81) is catalogued as a globular cluster in Ara. Its J2000 position is RA 17:25:29, Dec -48:25:19, corresponding to 261.3713 degrees RA and -48.4222 degrees Dec. The local catalogue places it about 18,300 light-years away. Its referenced angular extent is approximately 7.1 by 7.1 arcminutes.

Observing tips

StarWatchr rates this as an easy target at magnitude 7.8. It is associated with summer observing, with midnight placement typically strongest around June. From 52 degrees north its theoretical meridian altitude is about 0 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 -140.1 km/s. The SIMBAD record currently connects it to 430 bibliographic references.

At roughly 7.1 arcminutes across, it benefits from a narrower field and adequate image scale. Use the listed 7.1 by 7.1 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
