PR LUPI = NOVA LUPI 2011 = PNV J14542000-5505030
     As first reported on CBET 2796, Nicholas J. Brown, Two Rocks,
Western Australia, reported his discovery of a possible nova (mag
10.2) on two TMax 400 films taken on Aug. 4.73 UT using a 135-mm-
f.l. f/2 Canon camera lens.  Brown's approximate position for the
variable was R.A. = 14h54m20s, Decl. = -55o05'03" (equinox 2000.0);
he notes that nothing brighter than mag 11.7 appears on a film that
he took on July 5.85.  The variable was designated PNV
J14542000-5505030 when it was posted on the Central Bureau's TOCP
webpage, and based on the spectroscopic reports confirming the
object as a nova (see below), it has been assigned the permanent
GCVS designation PR Lup by N. N. Samus.  E. Guido, N. Howes, and G.
Sostero report that a CCD image taken of PR Lup remotely through
the 2.0-m "Faulkes Telescope South" (+ Bessel R filter) on Aug.
13.5 shows it at mag 8.4 and at position R.A. = 14h54m23s.09, Decl.
= -55o05'11".2 (equinox 2000.0; USNO-B1.0 catalogue reference stars).
Additional magnitudes for PR Lup from W. Liller, Vina del Mar,
Chile (85-mm-f.l. Nikon lens + Tech Pan film + orange filter):
July 20.042, [11.5; 25.989, 11.1; Aug. 1.008, 10.4; 13.988, 8.5.
J. Brimacombe, Cairns, Australia, remotely used a 40-cm RCOS
telescope at Macedon Ranges Observatory near Melbourne, Australia,
on Aug. 12.443 to find mag 9.6 and position end figures 23s.06,
11".2.  Additional observational information is provided on CBET
2796.
     F. M. Walter, Stony Brook University, reports that photometric
and spectroscopic observations were obtained using the SMARTS/Cerro
Tololo facilities, starting on Aug. 9 UT.  Photometry with the
1.3-m telescope (+ ANDICAM dual-channel photometer) shows maximum
light (V = 9.1, K = 6.2) within a day or two of Aug. 13.0 UT; by
Aug. 23.0, the nova had faded to V = 11.2 and K = 8.1.  Optical
spectroscopy with the 1.5-m telescope (+ RC specrograph) between
Aug. 9.0 and 22.0 shows the spectrum of a classical "Fe II"-type
nova near maximum light.  A similar assessment was determined by
H. L. Malasan, J. Suherli, and E. Wiyando, Bosscha Observatory,
Institut Teknologi Bandung, Indonesia; and A. Arai and H. Kawakita,
Koyama Astronomical Observatory, Kyoto Sangyo University, Japan,
from optical spectroscopy obtained on Aug. 16.6 UT at Bosscha
Observatory.  The spectroscopic details are given on CBET 2796.
