Like any astronomical target, J1550-5418 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.
J1550-5418 scores 115 points on Spacedle's rarity scale, which places it in the mythic tier.
That score comes from 3 science badges — Pulsar, Magnetar and Deeply embedded (high DM) — 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.
