After months near quiescence around V=18.3, the X-ray transient ASASSN-18ey = MAXI J1820+070 (ATel #11423, #11756, #12128, #12157, #12534) has brightened steadily to V=15.9 during the 12 days prior to JD 2458703. We will continue our small-telescope nightly time-series photometry for at least the next month. Such a rebrightening, long after the 2018 main outburst of this black-hole X-ray nova, warrants new coverage at all wavelengths.
