Subject: Poss. nova
I found what appears to be a nova at (2000) RA = 18h 0.1m; Dec -30d 54'.
Mag 9.2 with Tech Pan film and an orange filter. Image appears on two films taken at UT Apr. 15.354. Nothing brighter than mag 11.5 was at that position on a pair of films taken on Apr. 11.40. No bright asteroids are in the region.
If the weather stays reasonable, I will be able to get a better position and a spectrum tonight.
Observers, please confirm ! All the best, Bill
No known variable star, IRAS/MSX5C source, bright 2MASS source is present at this position. The object is very likely a nova or a related eruptive/cataclysmic object.

M. Fujii (Fujii Bisei Observatory) obtained the spectrum of the supposed nova (Nova Sgr 2002) on Apr. 18.80 UT.
Fujii reports that the following emission lines are present: strong H-alpha (FWHM=2800km/s), H-beta, Fe II (37,38,42,49,55,74), Na I (5890) and He I(7065). The object is an Fe II-class nova.
