Prior to discovery on 2018 March 31, four outbursts were
recorded by the ASAS-SN Sky Patrol (Shappee et al. 2014ApJ
...788...48S and Kochanek et al. 2017PASP..129j4502K):
2014 July 24, mag 13.1 V (superoutburst?);
2015 March 8, 13.7 V (normal outburst?);
2016 August 20, 13.3 V (superoutburst?);
2017 July 23, 13.6 V (normal outburst?).

The current outburst looks again like a superoutburst.
Time-resolved photometry is urgently required.

Clear skies,
Patrick
