Look for HR 2823 in the constellation CMa. At apparent magnitude 5.41, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 2823 is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. The visibility panel above works out tonight's viewing window for your saved location.
HR 2823 scores 50 points on Spacedle's rarity scale, which places it in the epic tier. Another 28 points would lift it into a rarer tier.
That score comes from 7 science badges — Star, Distant (over 1,000 light-years), Naked-eye visible, Hot blue B-type star, Bright giant, Blue-white star and Intrinsically luminous (Mv < −2) — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
