Processing of Pan-STARRS medium-deep field #1 (MD01) data has led to the discovery of an optical transient, designated PS10909010, at coordinates RA = 02:28:28.368, DEC = -04:04:44.08 (J2000) with an apparent brightness of r~21.5 mag on 2009 September 21 UT. A spectrum of the source obtained with the GMOS spectrograph on the Gemini-North 8-m telescope (PI: Berger) on 2009 October 2 UT reveals that the object is a type Ia supernova at z=0.27 about 3 to 8 days after maximum light. Narrow emission lines from the host galaxy confirm the redshift.
This discovery was made possible by the PS1 System and the PS1 Science Consortium (http://ps1sc.org).
