What constellations can you see at night now?

Do you mean what constellations can be seen in the south or what constellations are there in the southern sky?

At this time, you can see Cassiopeia, Andromeda, Pegasus, Perseus, Auriga, Tripod, Aries, Pisces (if the weather is fine), Taurus, Swan, Pisces and Capricorn in the south (I think this can be ignored).

Located in the southern sky are Pisces and Capricorn.

I only said those constellations that I think you can see, and I don't think you can see some of them, so I won't write them.
