> At UT 2012 Jan 10.275, we obtained a low resolution spectrum of the
> recent optical transient in NGC3239 (PSN J10250739+1709146; discovered
> by Moore, Newton and Puckett) with the Dual Imaging Spectograph on the
> ARC-3.5m telescope at Apache Point Observatory. We observe a blue
> continuum and P-Cygni Balmer features allowing us to classify this
> transient as a Type II supernova. The minimum of H-alpha absorption is
> blue-shifted by 9000 km/s. We thank Suzanne Hawley for facilitating
> these target of opportunity observations.
