Event: Nova in Lupus - Nova Lupi 2011 = PNV J14542000-5505030
Discovered by: Nicholas Brown, Quinns Rocks, Western Australia [vsnet-alert 13560]
Discovery Date: 2011 August 4.73 UT
Discovery Magnitude: magnitude 10.2 photographic unfiltered, on two films, using a 135F2 cannon lens and tmax 400 film
Coordinates: R.A. = 14 54 20, Decl. = -55 05 03 (equinox 2000.0)
Position from Mati Morel (Variable Stars South), Thornton, NSW, Australia, based on measurement of image by Roy Axelsen, Chapel Hill, Queensland, Australia, taken August 8.4674 UT
Spectra: Fred Walter, SUNY Stony Brook, reports (ATEL #3536) that a spectrum obtained 2011 August 9.0132 UT with the SMARTS 1.5m RC spectrograph at Cerro Tololo confirms that the object is an Fe II nova near maximum.

a. Initially announced by Nicholas Brown in [vsnet-alert 13560] and in AAVSO Special Notice #247  (Arne Henden).
b. Brown reports that nothing is visible down to 11.7pg on film taken on 2011 July 5.85 UT, and that no previous variable stars are reported near or at this position.
c. Kaufman reports a moonlight-affected, green-channel color image (DSLR at 55mm) and an enlargement with magnitudes are available at:
d. Morel notes that the nearest stars to above position in the USNO-B1.0 catalogue are :
B1.0 0349-0472601 (J2000) 14 54 22.92 -55 05 10.9 Ep. 1984.1 B2 =18.56 R2 =18.16
B1.0 0349-0472602 (J2000) 14 54 22.95 -55 05 09.6 Ep. 1985.9 B2 =19.56 R2 = 18.11
He also notes that, however, the DSS red plate shows only one (faint) object at the position of the B1.0 stars.
e. Daniel W. E. Green reports this object was listed on the Central Bureau for Astronomical Telegrams' Transient Objects Confirmation Page (TOCP)  as PNV J14542000-5505030. [This reference and identification was omitted from the email version of this Alert Notice.]
