We report discovery of a galactic nova candidate
TCP J18251276-2225293. The transient was discovered by
the NMW-TexasTech survey on 2026-08-19.1063 UTC
at an unfiltered magnitude of 9.4.
We obtained BVRI photometry with a 0.3-m telescope equipped with
a QHY268M CMOS camera at the Preston F. Gott Skyview Observatory
of Texas Tech University and found:
2026-08-19.2464 B = 9.0
2026-08-19.2472 V = 8.5
2026-08-19.2470 R = 8.0
2026-08-19.2539 I = 8.1
The photometric accuracy is limited by calibration uncertainties
and is expected to be about ten percent. The coordinates are
18:25:12.76 -22:25:29.2 +/-0.3" J2000 measured relative to UCAC-3
stars in the field. There is nothing in either the Gaia DR3 or
Pan-STARRS DR2 catalogs in the immediate vicinity of the transient,
implying an outburst amplitude of at least 10 magnitudes.
Follow up photometry and spectroscopy of the target
are highly encouraged.
