Ground-based photometric monitoring light curve of HD 86226. The large colored markers represent nightly mean magnitudes. The small gray markers represent individual exposures. The sigma-clipped mean magnitudes averaging the entire light curves and the ±1 σ_all ranges are represented with horizontal lines and shaded regions. Vertical lines correspond to HST observations; the last HST visit in January 2025 is not shown. We identify no evidence of stellar activity during the monitoring period.
