The Galactic nova PNV J15384000-4744500 was discovered by
R. Kaufman using DSLR camera images obtained on 2018-06-03.4306
with confirmation images, photometry and astrometry obtained by
S. Kiyota. The SMARTS (ATel #11681) and SALT (ATel #11684)
observations revealed a spectrum typical for a classical nova
near peak.
Swift observed PNV J15384000-4744500 for 1.9ks on 2018-06-06.188
The XRT detected no X-ray source at the position of the transient
with an upper limit of 0.0026 +/-0.0012 cts/s. Assuming power law
emission with the photon index of 2 and the total HI column density
in this direction to be 2.28x10^21 cm^-2 this translates to
the unabsorbed 0.3-10 keV flux limit of 1.6x10^-13 ergs/cm^2/s.
A bright ultraviolet source is visible on UVOT images at
the position 15:38:43.80 -47:44:41.0 +/-0.2" J2000 measured with
respect to UCAC3 stars in the field. The UVOT UVW1 filter magnitude
is 11.87 +/-0.02 (Vega system). The photometric error is likely
underestimated due to significant coincidence losses.
We thank the Neil Gehrels Swift Observatory team and PI, Brad Cenko,
for rapid scheduling of this ToO observation.
