We present the discovery of TUVO-21acq, a new transient which we detected in the UV using data from the UVOT aboard Swift. We detected two separate outbursts and used the UVOT data to constrain source properties, focusing on the amplitudes and timescales of the outbursts. To further characterise the source, we obtained an optical spectrum during quiescence with the Southern African Large Telescope (SALT; Buckley et al., 2006). The spectrum exhibited hydrogen Balmer series and helium emission lines, and a flat overall spectral shape. We confirm the nature of the source as an accreting white dwarf which underwent DN outburst based on photometric and spectroscopic properties.
