The nova candidate PNV J17140261-2849237 = TCP J17140253-2849233
was discovered by H. Nishimura, T. Kojima, K. Nishiyama and
F. Kabashima. A. Takao reports the transient (9.5mag) visible at
unfiltered images obtained on 2018-03-10.753 UT. Spectroscopic
observations with the 2m Liverpool Telescope confirmed
the transient to be a Fe II type nova (ATel #11398).
Swift observed the nova for 2.0ks on 2018-03-12.217, 35 hours after
the first optical detection. The XRT found no X-ray source at
the nova position with an upper limit of 0.002 cts/s. Assuming
power law emission with the photon index of 2 and full Galactic HI
column density in the source direction (2.45x10^21 cm^-2) this
translates to the unabsorbed 0.3-10 keV flux limit
of 1.3x10^-13 ergs/cm^2/s.
The simultaneously obtained UVOT image is distorted by a tracking
error preventing precision astrometry and photometry, but
the bright (W2=13.03+/-0.02) ultraviolet source is clearly visible
at the reported nova position.
We thank the Neil Gehrels Swift Observatory team and PI, Brad Cenko,
for rapid execution of this ToO observation.
