We detect the counterpart in all bands and measure an r-band magnitude of\n    \nr = 23.93 ± 0.22 AB mag.\n    \nThe magnitude is calibrated against the PS1 catalog and not corrected for Galactic extinction.\n\nWe thank Christoph Ries from the Wendelstein Observatory for obtaining these observations.",
