NOVA OPHIUCHI 2008
     The following Japanese observers have reported independent
discoveries on May 25 of an apparent tenth-magnitude nova:  K.
Nishiyama (Kurume, Fukuoka-ken) and F. Kabashima (Miyaki-cho, Saga-
ken) on 60-s frames taken with a 105-mm f/5.6 lens (communicated
by S. Nakano, Sumoto, Japan); H. Nishimura (Kakegawa, Shizuoka-ken;
via Nakano); and K. Haseda (Toyohashi, Aichi; via H. Yamaoka,
Kyushu University).  Nishimura and Haseda used 120-mm-f.l. camera
lenses.  Other confirming reports were received after word of the
object was posted on the Central Bureau's unconfirmed-objects webpage.
CCD position measured for the apparent nova by Nishiyama and
Kabashima (0.40-m f/9.8 reflector) on May 25.750 UT:  R.A. =
17h39m50s.93, Decl. = -23o50'00".9 (equinox 2000.0).  Other
measured position end figures:  Nishimura, 51s, 49'.1; Haseda, 47s,
50'28" (resolution 14"/pixel); S. Dvorak (near Orlando, FL, U.S.A.,
0.25-m telescope on May 26.30), 50s.90, 50'00".6; C. Jacques and E.
Pimentel (Belo Horizonte, Brazil, 0.25-m reflector remotely near
Mayhill, NM, U.S.A., on May 26.43), 50s.92, 50'01".1; E. Guido and
G. Sostero (Remanzacco, Italy, 0.25-m reflector, remotely near
Mayhill, NM), 50s.95, 50'00".9 (image posted at http://tinyurl.com/

otherwise noted):  1985 (no date), [19.5 (Jacques and Pimentel, red
Digitized Sky Survey); 1991 Aug. 11, [20: (Guido and Sostero, U.K.
Schmidt Telescope red plate); 2008 Mar. 8.82, Apr. 4.77, and May
14.70, [11.5 (Haseda); Apr. 27.094, [16.0 (H. Mikuz, Crni Vrh
Observatory; red magnitude); May 14.759, [12 (Nishimura); 19.752
and 20.694, [12.4 (Nishiyama and Kabashima); 20.745, [10 (Nishimura);
25.69, 10.3 (Haseda); 25.693 and 25.695, 10.2 (Nishiyama and
Kabashima); 25.706, 10.2 (Nishimura); 25.750, 10.2 (Nishiyama and
Kabashima); 26.30, V = 10.29, B = 11.72 (Dvorak); 26.31, B = 11.42,
V = 10.45, R = 9.81 (Guido and Sostero); 26.43, 10.4 (Jacques and
Pimentel).  Visual magnitude estimates by A. Jones (Nelson, New
Zealand):  May 26.40, 10.2; 26.45, 10.1.
