GCN Circ 25552) was observed at Stroncone \nObservatory (MPC 589) with the 50cm R-C telescope, a CCD SBIG camera\nand the I_Cousins filter. Nine frames with 300s exposure each were\nobtained: Bias, Flat and Dark current corrections were applied with IRAF\nstandard tasks.\nAperture photometry was performed with IRAF/apphot. The contribution\nfrom the underlying galaxy was subtracted assuming a symmetric light\ndistribution, and evaluated about 0.2 mag. Comparison stars were taken\nfrom PanSTARRS-DR1 (i') and GSC2.3.2 (N) with very consistent results\nbesides the zero point offset.\nMid-exposure time was 2019-08-30T00:47:15 UT; the magnitude of the GRB\nwas I_C=16.7 corrected for the galaxy contribution but not for reddening.",
