We obtained follow-up photometry of the Galactic Nova ASASSN-16kt (ATel #9538, #9539, #9550; CBET #4322) with a Celestron NexStar 4" telescope and a Canon EOS 300D camera observing from downtown Santiago (Chile), through variable clouds, on UT 2016 September 28.98 (JD = 2457660.47986). We extracted aperture photometry with IRAF on the RGB images and calibrated the results relative to BVr photometry of the nearby star HD137620 (B=7.688, V=7.692, r=7.862) from the AAVSO Photometric All-Sky Survey (APASS; Henden et al. 2015). The magnitudes for the nova are the following: B=7.90 +/- 0.08, V=7.88 +/- 0.08 mag, and r=7.14 +/- 0.16. These errors are only statistical and do not include uncertainties in the photometric calibration in a different filter system or other systematic uncertainties. These observations confirm the decline from peak reported in ATel #9550 and the AAVSO (~1.6 mag fainter in V in the last 3.2 days).
