Two USNO-B1.0 stars (both about 17 mag) are within 1" of the transient's position.
Spectroscopy, precise astrometry, and time-resolved photometry are required.
Clear skies,

Hats off to Hideo-san! Wonder why ASASSN and all these mega-survey telescopes failed to catch it?

I got PNV J17381927-3725077 at 12.2 vis at 16:18 11/06 UT. A 3 degree chart plotted on the co-ords gets a sequence. Very difficult because a long way from the transient field.

There is a new sequnece available for PNV J17381927-3725077.
Hi Jim,
thanks. Used the new sequence and measured the stars at 11.4 mag using a clear filter (CV).

K. Ayani, Bisei Astronomical Observatory (BAO) obtained a low-dispersion spectrogram (resolution 0.5 nm, range 400-800 nm) of this PNV with the BAO 1.01-m telescope. It has a prominent and broad H-alpha emission line (FWHM about 1800 km/s, equivalent width about 23 nm) and a broad H-beta emission line, which shows that the PNV is a nova in early phase. The spectrum ... is posted at
