Look for 36Xi 1Sgr in the constellation Sgr. At apparent magnitude 5.02, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 36Xi 1Sgr 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.
36Xi 1Sgr scores 62 points on Spacedle's rarity scale, which places it in the epic tier. Another 16 points would lift it into a rarer tier.
That score comes from 8 science badges — Star, Distant (over 1,000 light-years), Naked-eye visible, Toward the galactic centre, On the zodiac, Hot blue B-type star, Supergiant 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.
