Multi-wavelength light curves from MJD 59515.99 – 59526.10. Panels from top to bottom: H.E.S.S flux for CT1-4 and CT5 in 10⁻¹¹ cm⁻² s⁻¹, Fermi-LAT flux for both 12-h and 24-h binning in 10⁻⁶ cm⁻² s⁻¹, Fermi-LAT spectral index for 24-h binning, Swift-XRT flux in 10⁻¹² erg cm⁻² s⁻¹, Swift-UVOT flux in 10⁻¹² erg cm⁻² s⁻¹, and ATOM flux for V, B and R filters in 10⁻¹² erg cm⁻² s⁻¹. The double vertical dotted red lines denote the H.E.S.S. detection period, MJD 59521.93 – 59521.99. Only statistical errors are shown.
