Possible supernova in M61 (NGC 4303)
Following the posting on the Central Bureau's Transient Object Confirmation Page about a possible Supernova in the barred spiral galaxy Messier 61 (or NGC 4303 - TOCP Designation: PSN J12215757+0428185) we performed some follow-up of this object through a 0.10-m f/5.0 astrograph + CCD from MPC Code H06 (iTelescope, New Mexico).

On our images taken on October 30.5, 2014 we can confirm the presence of an optical counterpart with unfiltered CCD magnitude 13.2 and at coordinates:
R.A. = 12 21 57.61, Decl.= +04 28 17.8 (equinox 2000.0; UCAC-3 catalogue reference stars).
