Look for HR 2308 in the constellation Ori. At apparent magnitude 6.3, it is an easy target for binoculars.
Like any astronomical target, HR 2308 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 2308 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 7 science badges — Variable star, In Orion's hunting ground, Carbon star (sooty red), Bright giant, Deep red star, Gently variable and A named variable star — 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.
