If this magnitude means that of a possible SN, and if its host galaxy 
NGC4478 locates the same distance as M87, this possible SN seems to 
be too brighter to be typical SN II or SN Ib/c. And the host galaxy
is elliptical one. These suggests that, if it is really SN event, it 
should be of type Ia, possibly before the maximum. 

The identifications and following observations are extremely urged. 
SN Ia in Virgo cluster gives us the oppotunity to verify the
homogenuity of SNe Ia.
