POSSIBLE SUPERNOVA IN NGC 4303 (= MESSIER 61)
AAVSO Special Notice #389 carries a note that the CBAT Transient Object
Confirmation Page has an entry:

PSN J12215757+0428185 

relating to a possible supernova of unfiltered magnitude 13.6 in NGC 4303
found by Koichi Itagaki, Yamagata, Japan on 2014 Oct 29.8376UT.

Coordinates:  RA 12h21m57.57s DEC +04 28'18.5" (2000).
See: http://www.k-itagaki.jp/images/4303.jpg

This object has been submitted to VSX and assigned the name PSN
J12215757+0428185. Once it is approved, charts may be plotted using the
AAVSO Variable Star Plotter (www.aavso.org/vsp).

At this moment there is no AAVSO sequence, but one will be made available as
soon as possible.

Once this object has been added to AAVSO VSX and an AUID assigned,
observations may be submitted to the AAVSO International Database using the
name PSN J12215757+0428185. Please be sure to indicate what comparison stars
you used.

This AAVSO Special Notice was compiled by Elizabeth O. Waagen.

Ernesto Guido et. al. relays that following the posting 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 2014 October 30.5UT 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).
