Evolution of the Hα profile across 10 epochs from 2026 March to June, shown in velocity space relative to the rest wavelength of Hα. The P Cygni profile is present during quiescence and at the optical peak, weakens as the system fades, disappears before the second optical peak in April, and reappears in May.
