IAUC No. 6322 (D. Green) tells that Sakurai, Ibaragi, Japan discovered a possible "slow" nova in Sagittarius.
17h 52m 33s.5 -17o 40' 52" (J2000.0)
He estimated the object at photographic (Fuji G400 film) magnitude of 11.4 on Feb, 20.806 UT. The object seems to have started brighten at around 1995 Jan., when it was 12.5.
S. Benettei and H. W. Duerbeck report s spectrum taken by E. Cappellaro show a reddened early G-star with no prominent emission components. It may be a "slow" nova or a symbiotic nova.
Y. Kushida (IAUC 6223) reports an accurate astrometry of this object.

In IAUC No. 6325, S. Benetti is reporting high-resolution spectra, which showed pure absorption lines of He, C, N etc. From the slow brightening and spectral features, they suggest that the variable may represent a final helium shell flash as has been suggested for explanation of the V605 Aql (Nova Aql 1919) event. This suggestion has been supported by the discovery of a planetary nebula which had been presumably ejected from this object (cf. IAUC 6328 Duerbeck and Pollacco: press release).
