When and where to look for Corvus

Corvus crosses the meridian — its highest point in the sky — at local midnight around March, which makes the months from February to April the easiest time to find it in the evening. It spans declinations -24.7° to -16.5°, so visible from everywhere south of about 65°N.

The quickest way to find it is to open the live AR sky map and point your phone at the sky — if Corvus is above your horizon right now, its figure is drawn in the position it genuinely occupies above you.

Magnitude runs backwards: lower numbers are brighter, and anything below about 6.5 is beyond the naked eye under a dark sky.

What Corvus is made of

The catalogue lists 28 stars within Corvus, of which 28 are magnitude 6.5 or brighter — the limit of what an unaided eye picks up under a genuinely dark sky. The rest need binoculars or a telescope.

Spectral class is a temperature ordering, running from O at around 30,000 K down to M below 3,500 K. A constellation is a direction, not a group, so this is simply what happens to lie along that line of sight.

The closest catalogued star in this direction is Alchiba at 48.7 light years. The most distant is HD 104337 at roughly 3,167 light years — stars that appear side by side here are nothing of the sort.
