The optical transient TCP J00114297+6611190 was identified on 2020-07-27.9302 UT by S. Korotkiy at the unfiltered magnitude 12.9 (V zero-point). The discovery images were obtained with a 135mm f/2.0 telephoto lens + SBIG ST-8300M CCD camera as part of the NMW survey (Sokolovsky et al. 2014, ASPC, 490, 395).

TCP J00114297+6611190 was observed on 2020-07-29.025 with Transient Double-beam Spectrograph mounted on the 2.5m telescope of Caucasian Mountain Observatory of Sternberg Astronomical Institute, Lomonosov Moscow State University. The data reduction was performed with a custom python pipeline (Dodin et al. 2020, Astron. Lett., 46, 8, in press) using a combination of Ne-Kr-Pb lamp and telluric lines for wavelength calibration and BD+28 4211 as the spectrophotometric standard. The spectrum is dominated by H I, Fe II, and Na I P Cygni profiles. The absorption trough of the Halpha P Cygni profile is at a velocity of around -850 +/-100 km/s. The spectrum is that of a classical nova near optical peak.
