TCP J07134590-2112330</a> was discovered by Yuji Nakamura on 2018 March
24.5 UT as a 12 mag optical transient. We obtained spectroscopic observations
of TCP J07134590-2112330 with the Goodman spectrograph on the 4-m SOAR
telescope on 2018 Mar 25.1 UT, with a low-resolution spectrum (R~1200)
covering 3850--7850 A. The spectrum indicates that TCP J07134590-2112330
is a young classical nova, with strong hydrogen Balmer emission lines and
additional strong lines of [O I] and Fe II. The Balmer lines show P Cygni
profiles; the FWHM of the H alpha emission component is 1250 km/s, and
the absorption trough extends to -2000 km/s.</br>

Astrometry of the acquisition image implies that this transient is identical
to a source in the Pan-STARRS1 catalog with g=21.5 and r=21.2. The Pan-STARRS1
J2000 position of TCP J07134590-2112330 is RA = 07h13m45.843s , Dec = -21d12'31.28",
with a catalog uncertainty of about 25 mas per coordinate.

PS: I see that Paolo quotes this new nova in another post.
