Helsinki), Zipei Zhu (NAO/CAS), Dong Xu (NAO/CAS), report on \nbehalf of a larger collaboration:\n\nWe observed the bright optical counterpart (Siegel & Sonbas, GCN 24889) \nof GRB 190627A (Sonbas et al., GCN 24888) using the Nordic Optical \nTelescope (NOT) equipped with the StanCam imager, using the Bessel R and \nI filters. Observations were conducted starting on Jun 28.886 UT (1.415 \ndays after the trigger).\n\nThe optical counterpart is clearly detected in our images in both \nfilters. We measure a preliminary magnitude r = 20.2 +- 0.1 AB \n(calibrated against the Pan-STARRS catalog).",
