Left: one of the TRIPOL g-band images of Wolf 359 taken on 2023 February 22, with the target and two selected differential standard stars (S1 and S2) labeled. Right, top panel: raw light curves of Wolf 359 (green), the sum of the two reference stars (blue), and the individual reference stars (orange), in units of instrumental counts. Right, bottom panel: calibrated relative flux light curves from differential photometry. A flare event is clearly visible in Wolf 359 around 60 minutes after the start of the observation run. The two reference stars exhibit minimal variability, validating their use as stable differential standards. The same processing was applied to the data obtained in all other bands and on all other observation nights.
