Top: the ASAS-SN lightcurve of J0705+0612 in the last 10 yr. Middle and bottom: zoom-in view of the last few months with a collection of follow-up photometry. The black dashed line at MJD 60568 (2024 September 15) marks when the dimming becomes apparent in the lightcurve and the one at MJD 60822 (2025 May 27) marks the corresponding point of the egress. Teal lines mark our follow-up spectroscopy epochs.
