          NOVA SAGITTARII 1970 = SVS 1728.

The nova was found on a 8deg objective-prism plate
taken 1970 July 29 by R. Bartaja and T. Vashakidse at 
Abastumani with the 70-cm reflector. The approximate coordinates
as measured on the BD-Atlas are alpha = 18h27m3+/-0.1m, 
delta = -18deg48'+/-1'. (1855) The spectral region covered is 
lambdalambda3700-5000 at a dispersion of about 160 A/mm  at 
Hgamma. The magnitude of the nova on this plate is near m_pg
13m. The appearence of the spectrum is as follows: bright lines 
Hbeta, Hgamma, Hdelta; N_1 is fainter than Hbeta, the  intensity 
of lambda4363 is approximately equal to that of Hgamma, a faint 
broad lambda4640 is present. The spectrum seems to have been 
obtained at the beginning of the nebular stage, so that the star 
was probably about 5 magnitudes down from the maximum light. 
The nova is invisible on the spectral plates taken in 1968 with 
the same limiting photographic magnitude.
