Erigone

Given clear skies, observers would see Regulus disappear as the 45-mile-wide asteroid Erigone, which is too dim to spot on its own, passed in front of it.

The bright star Regulus will lie high in the sky toward the southwest on March 20 just after 2:06 am EDT, when the asteroid Erigone will occult it.

The space rock Erigone will pass between Earth and the star Regulus just after 2 a.m.

And Theopompus says that near the river Erigone all the water is sour; and that those who drink of it become intoxicated, just like men who have drunk wine.

His Erigone, of which a few fragments are also preserved, is sometimes spoken of as a separate poem, but it may have belonged to the Hermes, which appears also to have been known by other names such as Catalogi.
