Observing tips
This is rated as a very easy target at magnitude 4.5. It is associated with spring observing, with midnight placement typically strongest around March. 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 OpC. A published radial velocity value is -0.9 km/s. The SIMBAD record currently connects it to 192 bibliographic references.
Confirm the framing in the live sky atlas before choosing a field of view. Use the listed unknown arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
