Observing tips
StarWatchr rates this as a very easy target at magnitude 4.1. It is associated with autumn observing, with midnight placement typically strongest around September. From 52 degrees north its theoretical meridian altitude is about 0 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 GlC. A published radial velocity value is -17.2 km/s. The SIMBAD record currently connects it to 4193 bibliographic references.
Its roughly 43.8 arcminute span suits a medium field of view. Use the listed 43.8 by 43.8 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
