Dear vsnet members,

Akira Tago (Tsuyama, Japan) discovered a possible nova on two films
obtained at July 13.558 and 13.560 UT:

R.A.  19h07m40s  Decl. +12 32'15" (J2000)  mag 8.8

The photographs were taken by himself using a 55mm (f/3) lens and
T-max 400 film (unfiltered).  He also notes that no star is visible
at the position on the films taken on July 5 (limiting mag. is 11),
and July 9 (10.5).

Taichi Kato (Kyoto Univ.) points out there is no known variable star
nor IRAS source, which is likely to reach 8th mag., at the position.

I (Nakamura) have just observed this object, and confirmed its existence.
The following position was obtained from two CCD frames taken with a 60cm
(f/5.8) Ritchey-Chretien telescope at the Kuma Kogen Astronomical Observatory:

July 14.513UT
19h07m36.90s  +12 31'26.2"  (J2000)

Could someone take a spectrum of this object?

Best regards,
Akimasa Nakamura

Dear vsnet members,

I have just sent a following report to CBAT.

Congraturations, Mr. Tago!

K. Ayani and T. Kawabata at Bisei Astronomical Observatory (BAO),
Okayama, Japan, obtained a low resolution spectrum (470-680nm) of the
possible nova, which was discovered by A. Tago, on July 14.6 UT with
BAO 1.01-m telescope.  Strong, broad H-alpha and H-beta lines are
visible.  The H-alpha line has a FWHM of about 3400 km/s and a
equivalent width of about 50 nm.

Best regards,

Kazuya Ayani
Bisei Astronomical Observatory
