MAGIC and NuSTAR intra-night light curve between June 4, 2022 (MJD 59734) and June 5, 2022 (MJD 59735), corresponding to the IXPE 2 epoch. Upper panel: Light curve above 400 GeV obtained with MAGIC. A constant model fit is showed in dashed gray with the corresponding reduced χ². Lower panel: Light curves for the 3–7 keV and the 7–30 keV band taken by NuSTAR, and constant fits for both. Fluxes from both instruments are computed in ≈30 min time bins, except for the first bin that is ≈40 min long due to a limited exposure of NuSTAR around at the start of the MAGIC observation.
