AAVSO Alert Notice 553

September 27, 2016

Nova Lup 2016 = PNV J15290182-4449409 = ASASSN-16kt

Event: Nova in Lupus

Discovered by: All Sky Automated Survey for SuperNovae (ASAS-SN)
(K. Stanek (Ohio State University) et al., ATel #9538; reported
to CBAT via J. Strader (Michigan State University))

Discovery magnitude: 9.11 V +/- 0.01, using ASAS-SN robotic 14-cm
telescopes

Discovery date: 2016 September 24.010 UT

Coordinates (2000.0): R.A. 15 29 01.82 Dec. -44 49 40.9

Spectra: A spectrum obtained on 2016 September 24.43 UT by T.
Bohlsen (Armidale, NSW, Australia, using a LISA spectrograph on a
C11 SCT R=1500 but very noisy due to passing cloud) shows Halpha
emission, indicating that this object is a nova. His spectrum may
be viewed at:

Observing recommendations: Observations of all types (visual, CCD,
DSLR, spectroscopy) and all bands as instrumentation permits are
strongly encouraged as this bright nova evolves.

Dr. Laura Chomiuk (Michigan State University) posted to the AAVSO
Novae forum that she is "...working with a collaboration of
observers and theorists to test a recent theoretical prediction of
Ken Shen's---that novae should show fast periodic oscillations in
their optical light curves, if gravity waves help expel the
envelope." She asks if any observer with "...access to a high-speed
photometer (say a photo-multiplier tube)...could observe this
target for an hour or two. Even exposure times as long as 1 second
would be useful, although several exposures per second would be
better." If you have access to a high-speed photometer, please
contact E. Waagen (eowaagen@aavso) for details on reporting these
data.
