   No known minor planet seems to be present at this position.  Further check with a large instrument will be required.

     The object in Paulo's image looks suspiciously elongated as though it were an artifact in the CCD (directly along a column/row). The Minor Planet Center's 'MPchecker' shows no asteroids with orbits in the vicinity.  (http://scully.harvard.edu/~cgi/CheckMP)

The suspect is a SN ... I just imaged it and it is still there. I will send in a report real soon.

  NGC 3190 seems to be as near as the Virgo cluster, so it can reach mag 12 or so if it is an unreddened SN Ia.  The object is, however, nearly superimposed on the dark lane.
