What is Subra

Subra, also «al-zubrah» in Arabic — «the mane» — completes the lion's ruff in the constellation Leo, just behind the front paws of the celestial beast. It is a white star 130 light-years away, bright and steady, with no striking singularities: a precise, almost geometric point in the spring sky. Its light set out while the first electrical transformers were still being invented and household electricity remained a noisy fairground promise.

Where it is and when to see it

Subra lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is February: 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

Write my signature

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.
