H. Yamaoka, Kyushu University; and H. Naito and N. Tokimasa, Nishi-Harima Astronomical Observatory, report that a rather noisy, low-resolution spectrum (range 420-690 nm; R = 1000 at 500 nm) taken of 2006at on Mar. 8.8 UT with the 2.0-m NAYUTA telescope shows a rather featureless blue (blackbody-like) continuum with possible very broad features (either absorption valleys or emission troughs, which suggests that it may be a very young supernova. On the slit-viewer unfiltered image, the new object was at mag about 16.7. Nothing is visible at the location of 2006at on a DSS image from 1997 Apr. 13 (limiting red mag about 20); the host galaxy is hard to identify on the DSS image because it is very diffuse. A SDSS color-composite image taken in 2001 also shows no point source down to mag about 21.
