The bright, nearby γ-ray burst (GRB) 060614 does not fit in either of the two duration classes. Its ∼102-s duration groups it with long-duration GRBs, whereas its temporal lag and peak luminosity fall entirely within the short GRB subclass. This opens the door on a new GRB classification scheme that straddles both long and short bursts.
