Information about the discovery of a bright possible nova in Centaurus
by J. Seach, Chatsworth Island, NSW Australia, designated PNV J13544700-5909080
was posted here.
I confirm the presence of the bright object (R ~ 5 mag) on 0.3-s R-band images obtained
using the Danish 1.54-m telescope at La Silla on 2013 Dec. 3.361 UT. The object
is located at R.A. = 13h54m45s.34, Decl. = -59o09'04".2 (equinox 2000.0).
The object is very probably identical with a ~ 15 mag star
USNO-B1.0 0308-0442031 = 2MASS 13544534-5909040 = UCAC4 155-128029,
which I identify as a probable progenitor of the possible nova. If the identification
is correct, the estimated amplitude of the outburst is ~ 10 mag, which is consistent
with the outburst of a classical nova.
