LQ SAGITTARII
Further to the announcement on E856, U. Munari and T. Zwitter,
Asiago Astrophysical Observatory; and A. Bragaglia, Astronomical
Observatory, Bologna, communicate:
"A low-resolution, optical/near-infrared spectrogram of LQ Sgr
(= Nova Sgr 1897), recently announced as undergoing a
symbiotic-nova outburst, was secured on July 14.1 UT with the
Boller & Chivens spectrograph of the 1.5-m European Southern
Observatory telescope. The spectrum is typical of a Mira variable
close to maximum brightness. It does not resemble that of any known
symbiotic or classical nova at maximum or declining phases. We
therefore suggest that LQ Sgr is a normal Mira variable."
