Theta 1 Microscopium
Variable starWhat is Theta 1 Microscopium
θ¹ Microscopii is a white star with subtle variations in brightness, resident of the Microscope, one of the modern constellations invented by the abbé Lacaille in the 18th century during his expedition to the Cape of Good Hope. Lacaille drew scientific instruments there —compass, telescope, reticle— which still populate the southern sky today. θ¹ is a small, discreet flame in that celestial cabinet of the Enlightenment.
Where it is and when to see it
Theta 1 Microscopium lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is August: 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.
