Today's update to the Current Bright & Interesting Novae & Supernovae in ST4 Visual reports a new supernova in M 33 in Triangulum. The supernova is currently 13.5 magnitude.
This object is currently well placed for northern hemisphere evening viewing.

that sounds awfully faint for an SN in M33. Could it just be an ordinary nova?
Owen,
All I know is what ST4 Visual told me. Did you check out Greg's link to the discovery page?
Phil S.
I think its a Nova, but we won't be sure until someone gets spectra. Its actually labeled as a Nova but showing up classified as a an SN.
Actually ST4v refers to this object as a Nova of type Supernova. It's quite a distance from the center of M 33 so hopefully not heavily obscured by dust. How bright did SN 1987A in the LMC get? Is it in the SkyTools database? I couldn't find it using the Designation Search.

How bright should a Type Ia supernova be at the distance of M 33?
Phil S.
well given S And in M31 reached about 6 one would assume the same kind of range. SN1997A was naked eye when it was discovered. It will still a binocular object when I saw it later in the year.. However given M33 one would expect some variant of a Type II SN from a core collapse object. SN 1987A was a core collapse SN from a blue supergiant so one would assume Type II or one of the Ib or Ic classes. A search suggests a peculiar Type II
How bright should a Type Ia supernova be at the distance of M 33 or was S And also a Type Ia?
