What is Meridiana
Meridiana crowns the small Southern Crown, a white A-type star 125 light-years away. The constellation is modest but ancient, already named by Ptolemy, and the ancients pictured it as a wreath fallen at the feet of the neighbouring centaur. Its Latin name evokes midday and the meridian line of the sky. Meridiana's light travels in silence for a century and a quarter before settling on the human eye — almost a direct echo of the nineteenth century.
Where it is and when to see it
Meridiana lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is July: 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.
