Similar to Figure 1, we show the WISE light curves of four representative outburst galaxies in our MIRONG sample. The estimated magnitudes at the quiescent phase are shown with dashed blue and red lines. The vertical green dashed lines mark the boundary of the quiescent and outburst stage. Object SDSS J0103+1401 shows very fast rising followed by a relatively stable high state, in contrast with SDSS J0205+0004, which also displays fast rising but immediate declining. The other two objects show slower rising, in which SDSS J0120–0829 has manifested itself as a complete flare in terms of both rising and declining (Sun et al. 2020).
