GCN 42060), obtaining\na series of unfiltered images starting at 20:25:24 UT, i.e.\n~10.5min post trigger. \n\nWe clearly detect the optical transient reported by Palmerio et\nal. (GCN 42061) and Turpin et al. (GCN 42062). At the combination\nof 9 x 60 s images (Tmid=T0+23.5min) we measure the optical\nafterglow with the brightness r = 17.8 +/- 0.2 (AB) as calibrated\nagainst Atlas-REFCAT (Tonry et al. 2018, ApJ, 867, 105).\n",
