High-cadence V-band photometry around the dip observed in GOTO0650 from AAVSO, LCO, pt5m, and TTT. The blue curve shows a spline interpolation of the data. The vertical dashed line shows the initial onset of superhumps as the dip began. The g−r and r−i colour indices show no significant evolution through the dip. The dip shows a marked asymmetry, with a slow ingress and rapid egress. High-amplitude superhumps with an amplitude of ≈0.1 mag are visible immediately after the dip.
