GCN 23232; D'Ai et al., \nGCN 23236) with the 0.8m T80 telescope of the Javalambre Astrophysical \nObservatory (Teruel, Spain). Observations consisted of a series of 3x300 \ns griz exposures, starting at 22:47:49 UT  on September 16 (2.18 days \nafter the GRB detection). The afterglow is clearly detected in all \nstacked images. We measure the following magnitudes (AB system):\n\ng' = 20.73 +/- 0.05 mag at 2.1875 days,\nr' = 20.27 +/- 0.08 mag at 2.2003 days,\ni' = 19.94 +/- 0.07 mag at 2.2260 days,\nz' = 19.62 +/- 0.07 mag at 2.2413 days,\n\nas compared to nearby PANSTARRS stars.",
