Look for HR 1129 in the constellation Cam. At apparent magnitude 4.78, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 1129 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 1129 scores 32 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 2 points would lift it into a rarer tier.
That score comes from 6 science badges — Star, Naked-eye visible, Never sets (northern circumpolar), White A-type star, Main-sequence 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.
