V567 NORMAE = TCP J16272388-4601564 = NOVA NORMAE 2023
     A new variable (mag 14.9) was discovered by a team of observers (C.
Jacques, C. Colesanti, C. Barreto, E. Pimentel, J. Ribeiro, M. Domingues, J.
Amancio, L. Amaral, P. Holvorcem, and T. Napoleao) on three 10-s unfiltered
CCD exposures (limiting mag 16.5) obtained on June 27.099 UT with a 0.28-m
f/2.2 astrograph in the course of the Brazilian Transient Search at the
SONEAR2 Observatory in Belo Horizonte.  The position of the variable was
given as R.A. = 16h27m23s.88, Decl. = -46d01'56".4 (equinox J2000.0), and
when the object was posted at the Central Bureau's TOCP website, it was
automatically given the provisional designation TCP J16272388-4601564.
Nothing is visible at this position location on the previous frames (limiting
mag 16.5) taken on 2023 June 10.086.
     A. Pearce (Nedlands, Western Australia) reports position end figures
23s.90, 57".0 and unfiltered magnitude 13.9 from a CCD image taken on June
28.942 UT with a 0.50-m reflector at Skygems Observatory, Namibia (Gaia DR2
star positions; APASS V magnitudes for comparison-star magnitudes).  Pearce
adds that a 20th-mag star (Gaia DR3 5942396118015840768) lies close to the
position of TCP J16272388-4601564.
     S. Kiyota (Kamagaya, Japan) reports the following magnitudes for
TCP J16272388-4601564, obtained with an iTelescope 0.5-m f/6.8 CDK telescope
at the "Deep Sky Chile" observatory in the Rio Hurtado Valley, Chile, on
June 29.144 UT:  B = 16.02, V = 14.41, I_c = 11.77.  He has posted an image
at website URL https://meineko.com/ccd/TCP_J16272388-4601564.jpg.
     F. D. Romanov (Yuzhno-Morskoy, Nakhodka, Russia) reports his photometry
of TCP J16272388-4601564 from 300-s images obtained remotely using an
iTelescope 0.51-m f/6.8 "Corrected Dall-Kirkham" telescope at "Deep Sky Chile"
in the Rio Hurtado Valley:  July 3.144 UT, V = 15.45; 3.148, B = 17.23; 3.152,
R_c = 13.64; 3.156, I_c = 12.00.
     E. Aydi et al. (cf. URL https://www.astronomerstelegram.org/?read=16111)
have reported that spectroscopy obtained on July 1.96 UT with the 11-m
Southern African Large Telescope at Sutherland (range 380-890 nm; resolution
14000) shows P-Cyg lines of H Balmer, Fe II, Na I, and O I; the P-Cyg
absorption troughs are blueshifted by about 550 km/s, and the observers note
that the spectrum is that of a classical nova near peak brightness.
     E. Kazarovets writes that the permanent GCVS designation V567 Nor has
been given to this nova.
