Light curve of XN Mus 199

Light curve of XN Mus 1991. The slow variation over one phase is from the ellipsoidal modulation as in A0620-00. Large amplitude aperiodic variability is dominant, to the extent that the contribution from the ellipsoidal variation is not obvious. The large and extended flare at the end represents a net increase of about 40 percent, with an e-folding time of ~50 seconds.
