POSSIBLE NOVA IN AQUILA
In the absence of access to RLSAC, Gary Poyner has forwarded the
following messages issued from NovaNet:

"Minoru Yamamoto, 11-4 Nishi-Shaguchi, Doi-cho, Okazaki-shi 442-02
Japan, reports his discovery of an apparent nova with a 300-mm
(focal length) f/4 camera + T-Max 400 film + PO0 green filter
at R.A. = 19h10m.5, Decl. = +1 28' (equinox 1950.0).
Magnitude estimates: May 14.644 UT and May 14.647 UT, 7.6
(Yamamoto, photographic); May 14.779 UT, 7.6 (Yukio Sakurai, Mito,
Japan, cf. IAUC 4492; 135-mm f/2.8 camera + Fuji HG-400 color film;
by re-examination of his exposure on Yamamoto's discovery);
May 15.604 UT, 7.9 (Yamamoto, visual); May 15.648 UT, 7.6
(Yamamoto, photographic). Yamamoto notes that no object appears to
mag 10 on Apr. 17.780 UT with the same instrument.
Yamamoto and Sakurai report that the color is not reddish.
Tomohiro Hirayama National Astronomical Observatory, Mitaka, Tokyo

In response to this the Editor alerted Mike Collins, Everton, Beds,
UK to establish if he had photographs of the object. He has
responded confirming that on two photographs for the UK
Nova/Supernova Patrol of 1993 May 15.009UT (3m42s exposure) and
15.011UT (3m03s exposure) there is an apparent new object of
magnitude 7.6pv.(Kodak 2415, hypered, 135mm telephoto lens f2.8).
By reference to three SAO stars, Mike Collins calculates the
following position:

RA 19h 10.57m DEC +01 29.27' [1950]

An asteroidal search by the Editor and independently by Mike
Collins using AST.EXE by Nick James shows no candidate.

A search of GCVS IV, NSV and IBVS Name Lists to No 71 by the Editor
also shows no known variable star.
