Abdi\n(American University of Sharjah, UAE) report:\n\nAs a follow-up to our first observation of GRB 231117A, performed on Nov.\n17, 2023 (GCN 35084 <https://gcn.nasa.gov/circulars/35084>), we again\nobserved the field with our 0.36m f/7.7 robotic telescope, on Nov. 18,\nstarting at 15:50 UT using an (Ic) filter.\n\nWe again detected a faint object at the same location of the source SDSS\nJ220933.34+133119.5 (PS1 ID = 124223323889577032), which is listed in the\nPan-STARRS catalogue with imag = 21.5, and in the SDSS catalogue with imag\n= 20.9. The coordinates of the detected object are: R.A. (2000) =\n22:09:33.36, Dec. (2000) = +13:31:20.1, which is consistent with the\ncoordinates of the candidate optical source reported by Yang et al. (GCN\n35083 <https://gcn.nasa.gov/circulars/35083>).\n\nThe following table summarizes the results of both nights using the Atlas\ncatalogue as a reference:\n---------------------------------------------------------------------------\nObsTime (mid), T(Mid)–T(0), Exposure, Filter, Mag, RMS, Limiting Magnitude\n---------------------------------------------------------------------------\n2023-11-17 15:37:30Z, 12.6 h, 33x180s (stacked), Ic, 19.85, 0.20, 20.2\n2023-11-18 15:50:06Z, 1.53 d, 40x180s (stacked), Ic, 19.78, 0.21, 20.4\n---------------------------------------------------------------------------\nThe magnitudes are not corrected for galactic extinction.\n",
