Long duration Gamma-Ray Bursts (GRBs) have been strongly connected with core collapse supernovae, so it was surprising when the recent GRB060614 (with a reported redshift of 0.125) was found to have no visible supernova to deep limits. Three separate groups have reached the same conclusion that this event forces the existence of a new previously-unsuspected class of GRBs. The problem with this conclusion is that the redshift is not secure, as the measured galaxy emission lines simply give the redshift of the brightest galaxy near the line-of-sight to the GRB afterglow, and indeed the GRB position lies completely outside the galaxy. Fortunately, eight different luminosity indicators are known which can give the luminosity (and hence redshift...
