AT 2016blu has undergone five additional outbursts since its last major event in 2023 May/June (M. Aghakhanloo et al. 2025). Nearly all of these outbursts were monitored by AAVSO amateur astronomers (Alert Notice 847). The red dashed line indicates the expected time of the outburst derived from the most likely period of ∼113 days, tied to the 2012 January outburst. The brown dotted line marks the expected time of the outburst derived based on the secondary peak in the period analysis at ∼38.5 days (M. Aghakhanloo et al. 2023b). The times of the closest optical peaks to the expected outburst are indicated at the top of each figure.
