[size=13.3333px]Event: Nova in the Small Magellanic Cloud (Tucana)

[size=13.3333px]Discovered by: the MASTER-OAFA auto-detection system (reported by
[size=13.3333px]V. Shumkov (Lomonosov Moscow State University) et al. in ATel #9621)

[size=13.3333px]Discovery magnitude: 10.9 unfiltered CCD

[size=13.3333px]Spectra: Spectroscopy indicating that MASTER OT J010603.18-744715.8
[size=13.3333px]is a classical nova was obtained 2016 Oct 14.70 UT by S. C. Williams
[size=13.3333px](Lancaster Univ.) and M. J. Darnley (Liverpool John Moores Univ.)
[size=13.3333px](ATel #9628) with the FLOYDS instrument on the 2m Faulkes Telescope

[size=13.3333px]N. P. M. Kuin (Univ. College London-Mullard Space Science Lab.)
[size=13.3333px]et al. (ATel #9635) report that 500 seconds of observations by
[size=13.3333px]Swift centered on 2016 Oct. 15.3056 UT did not detect X-rays.

[size=13.3333px]Observing recommendations: Observations of all types (visual, CCD,
[size=13.3333px]DSLR, spectroscopy) and all bands as instrumentation permits are
[size=13.3333px]strongly encouraged as the nova evolves.

[size=13.3333px]a. Most of the information in this Alert Notice is taken from ATel
[size=13.3333px]#9621 ([size=13.3333px]http://www.astronomerstelegram.org/?read=9621[size=13.3333px]), #9622,
[size=13.3333px]#9628, #9631, and #9635.

[size=13.3333px]b. P. Mroz and A. Udalski (Warsaw Univ. Obs.; on behalf of the OGLE
[size=13.3333px]team) (ATel #9622) report the progenitor was clearly visible in
[size=13.3333px]OGLE images at position end figures 03.27s, 15.8", mean magnitude
[size=13.3333px]I = 20.84, and mean color (V-I) = 0.16 mag. They also report the
[size=13.3333px]progenitor showed semiregular variability on a timescale of 20-30
[size=13.3333px]days.

[size=13.3333px]c. Shumkov at al. (discovery image, 2016 October 14.19341 UT) give
[size=13.3333px]position end figures 03.18s, 15.8".
