The local catalogue places it about 10,000 light-years away. Its referenced angular extent is approximately 120 by 60 arcminutes.

Observing tips

This is rated as a moderate target at magnitude 4.6. It is associated with summer observing, with midnight placement typically strongest around June. From 52 degrees north its theoretical meridian altitude is about 19.5 degrees; local horizons and the live altitude chart determine the practical window.

Its brightness makes it a practical binocular or small-telescope candidate when it is well above the horizon.

What to expect

The SIMBAD classification for the matched source is As*. The SIMBAD record currently connects it to 54 bibliographic references.

At roughly 120 arcminutes across, it favors a wide-field imaging setup. Use the listed 120 by 60 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
