NOVA NORMAE 2005
     A. Ederoclite, E. Mason, and T. H. Dall, European Southern Observatory
(ESO), report spectroscopic confirmation of Liller's nova (cf. CBET 121, 123)
with the 3.6-m ESO telescope (+ HARPS; range 380-690 nm; resolution 100000).
The nova appears dominated by very strong H_alpha emission.  Low-ionization
emissions lines from Fe II (multiplets 27, 28, 37, 38, 42, 48, 49, and 74)
and Na I are clearly visible.  The Balmer and Fe II lines are flanked by weak
P-Cyg profiles that indicate an average expansion velocity of 1100 +/- 100
km/s.  The Na I interstellar lines appear saturated, thus suggesting a high
absorption/reddening.
     Further to CBET 121, W. Liller reports the following CCD magnitudes
of N Nor 2005 obtained on Mar. 20.326 UT with a 0.20-m Schmidt camera:
V = 10.10 +/- 0.05; B = 10.90 +/- 0.06.
     Visual magnitude estimates:  Mar. 20.195 UT, 10.1 (R. Y. Shida, Sao
Paulo, Brazil); 20.880, 10.1 (A. Pearce, Nedlands, W. Australia.
