We conducted follow-up imaging observations of MASTER OT J191310.16-472458.8 (AT2020rpo; ATEL #13954) using the 1.9 meter telescope at the South African Astronomical Observatory as part of a live observing session during the Global Relay of Observatories Watching Transients Happen (GROWTH) virtual astronomy school. A series of exposures was taken in the r-band (43x10s), u-band (3x60s), g-band (3x20s), i-band (3x20s), and z-band (3x20s), beginning at approximately 19:27:40 UT on 2020-08-19. We obtain the following preliminary photometry:
u = 16.06 +/- 0.08
g = 16.09 +/- 0.07
r = 16.44 +/- 0.05
i = 16.92 +/- 0.08
z = 17.02 +/- 0.05
The blue colors are consistent with this transient being a dwarf nova eruption from an uncatalogued cataclysmic variable.
