The Nearby Supernova Factory reports the discovery of supernova SNF20060524-023 (coordinates RA 13:21:49.14 DEC -23:51:04.6 J2000.0) in images obtained May 25.2 UT at an approximate magnitude of 19.0 (calibrated to R) using the QUEST II camera on the Palomar Oschin 48-inch telescope as a part of the JPL Near-Earth Asteroid Tracking component of the Palomar-QUEST Consortium. A spectrum (range 320-1000 nm) of this object, obtained May 26.3 UT with the Supernova Integral Field Spectrograph on the University of Hawaii 2.2-meter telescope, reveals it to be a Type II supernova at an approximate redshift (measured from the peak of its H-alpha feature) of z = 0.04. The H-alpha feature is in net emission, with almost no absorption feature visible. H-beta and H-gamma P Cygni profiles are also discernible on the blue continuum.
