SN 2000Q IN ANONYMOUS GALAXY

Y. Sato and W. D. Li, University of California at Berkeley, on behalf of the Lick Observatory Supernova Search (cf. IAUC 6627, 7126) with the 0.8-m Katzman Automatic Imaging Telescope (KAIT), report the discovery of a supernova in an anonymous galaxy that is about 218" east and 7" south of the galaxy NGC 6079. The new object was discovered on an unfiltered image taken on Mar 12.5 UT (mag about 17.8). It is located at R.A.=16h05m11s.85, Decl.= +69 39'51".5 (equinox 2000.0), which is 4".1 east and 1".6 north of the nucleus of the anonymous galaxy. An unfiltered image on Mar 1.5 UT showed nothing at the position of the new object (limiting mag about 19.0). A. V. Filippenko and A. L. Coil, also of Berkeley, report that uncalibrated CCD spectra (range 330-1000 nm) obtained on March 15 UT with the Shane 3-m reflector at Lick Observatory reveal that the supernova is of Type Ia, possibly subluminous, with quite prominent Si II features at rest wavelengths of 590 and 615 nm. The very approximate recession velocity derived from the Si II observed wavelengths is 6000 km/s.
