How to find Leo in the starry sky

On a spring night, after finding the beta star of Leo through the spring triangle, a big star to the east of it is all Leo. Leo can easily observe that in Leo, the delta, theta and beta stars form a remarkable triangle, which is the back and tail of the playful Leo.

These six stars from ε to α form the shape of a sickle, which is also like a reverse question mark. This is the lion's head. You can find it when the Polaris connecting Ursa major, that is, the two stars at the mouth of the spoon, extend in opposite directions to Polaris.

Latitude varies between 82 north latitude and 57 south latitude, and you can see the whole picture of Leo. Leo transits at midnight every March 1 Sunday. For mid-latitude observers in the northern hemisphere, Leo can be observed at night from the middle of winter to the end of spring, but the best observation month is April.
