Straight line and power law functions fitted to the decline of the 2020 outburst as observed in the u′-band. The black vertical line indicates where the fit starts. Only the data from this point onwards are fit as the rise of the outburst was hidden during sunblock. The fainter functions plotted on the left-hand side show the best fit functions mirrored for comparison with the data points before the outburst was observed. This implies an asymmetric outburst with a faster rise than decline.
