We obtained 28 \nframes in the Sloan r band, starting at 15:24:17 UT on 2020-08-30, i.e., \nabout 1.058 d after the BAT trigger.\n\nPreliminary photometric measurements are as follows:\nFilter\t        T_exp/s\tT_mid/d\tMag\t     Mag_err\nSDSS-r\t8x120\t1.062       >20.6\nSDSS-r\t20x120\t1.307       21.20        0.16\n\ncalibrated with nearby Pan-STARRS stars.",
