Variable starWhat is HIP 16339
Horologium is the pendulum clock that Lacaille traced in the 18th century while mapping the southern sky, a modern and sparsely populated constellation. There shines this white A-type variable, whose brightness shifts to a rhythm still catalogued by modern photometric networks. Its light left the star around 1633, when Galileo was being condemned by the Inquisition for defending the heliocentric system.
Where it is and when to see it
HIP 16339 lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is October: 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.
