(fwd) V4739 Sgr (Nova Sgr 2001-2) Liller's observation and spectroscopy

Dear all -

Regarding the new Nova Sgr 2001-2:

Broadband-V photometry with CCD by Wm. Liller, Vina del Mar, Chile: Aug
28.048 UT,  V(bb) =3D 8.55; 28.116, 8.20 (through clouds).

Nothing brighter than magnitude 12.0 appears at the position of the nova on
films taken by him on Aug 18.04.

A low-dispersion CCD objective prism spectrogram taken through clouds at
Aug 28.111 with a 0.20 m Schmidt shows H-alpha in emission at more than
twice the brightness of the surrounding continuum.  H-beta is also clearly
seen.  


My sincere heartiest congratulations to Don Alfredo Pereira for his
discovery, especially since it was (1) a visual discovery and (2) made at
an altitude much lower than it would have been here in Chile!

All the best to all,  Bill Liller
