Upsilon Coronae Borealis
What is Upsilon Coronae Borealis
Upsilon Coronae Borealis is a white type-A star some 667 light-years away, in the Northern Crown —that small semicircle of stars Greek myth identified with the diadem of Ariadne, cast into the sky by Dionysus. Its light set out towards us in the fourteenth century, when Europe was traversing the Black Death and astronomy was still inseparable from horoscope and liturgical calendar.
Where it is and when to see it
Upsilon Coronae Borealis lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is May: the Sun sits at the opposite point of the sky and the star culminates around midnight. How high it climbs above the horizon depends on the latitude you watch from.

The signature wall
Stelvia's sky works like a signature wall: anyone can leave their name and a message on a real star, and that signature goes up on the map for everyone to read. Signing is free.
A signature without a lock can be replaced by someone else's. The lock makes the signature permanent and lets you choose a symbolic name for the star, always shown next to the star's catalogue identifier. How the lock works

A public signature from a real person. The chosen name is a symbolic denomination within Stelvia, with no official standing or IAU recognition: the sky is not for sale and belongs to no one.
