We report ASAS-SN photometry of the Galactic nova TCP J17394608-2457555 (CBAT; ATel #10366). ASAS-SN recovered the source with a first detection (V=14.9) on Apr 21.43 UT, 17 days before the discovery by K. Itagaki. The subsequent light curve shows substantial variability between V~14 and V~16. The epoch in which the nova is brightest is Apr 30.24 (V=14.1) but there is, as of yet, no well-defined peak in the light curve. This optical variability around maximum resembles some recent novae, such as the gamma ray-detected nova V1369 Cen (Cheung et al. 2016, ApJ, 826, 142).
