“Up” is the highest the centre of each pattern gets above the horizon tonight — your fist at arm's length spans about 10°. Directions are where to face when it's best placed.
Low on the horizon from Seoul
These clear the horizon but stay low, so trees and buildings may hide them: Leo (~7°, western) · Orion (~4°, eastern) · Gemini (~3°, north-eastern).
Out of reach from Seoul
At Seoul's latitude these never climb above the horizon, so you can't see them from here at any time of year: Centaurus, Crux, Canis Major, Carina. To catch them, you'd need to travel toward the Southern Hemisphere.
