Subjects:Optical, Nova
A spectrum obtained at 0:19 UT on 2011 9 August with the SMARTS 1.5m RC
spectrograph at Cerro Tololo confirms that the eruptive object in Lupus
(AAVSO special notice 247; vsnet-alert 13560; 13569) is an Fe II nova near
maximum. The spectrum (3700-5400A at 4.1 A resolution) shows the Balmer
lines of hydrogen (H-beta through H-10), and Fe II multiplet 42, in emission
with P Cygni absorption components at a velocity of about -1000 km/s.
The equivalent width of H-beta is about -130 A.

I confirm that the eruptive variable in Lupus, reported as a possible nova
(AAVSO Special Notice #247; vsnet-alerts 13560 and 13569) is an Fe II nova
near maximum. A low dispersion blue spectrum (4.1A resolution; 3700-5400A)
obtained with the SMARTS 1.5m RC spectrograph at Cerro Tololo, Chile, on
2011 August 9.013 UT shows emission lines of the Hydrogen Balmer series
Hβ through H-10, and of Fe II multiplet 42 atop a flat continuum.
Hβ has an equivalent width of -130A. The strong emission lines have
P Cygni profiles, with absorption components blueshifted by about 1000
km/s
