The Comae Berenicids were first detected within the framework of Harvard Radio Meteor Project. The shower's existence was discovered by Richard Eugene McCrosky and A. Posen in 1959.[5] The Comae Berenicids have an orbit very similar to the December Leo Minorids often leading to confusion between the two meteor showers.
