Kreykenbohm (FAU), J. \nWilms (FAU) report:\n\nThe location of the Fermi/GBM long duration GRB 200120A (#26831, #26840, \n#26851, #26856, #26857, #26974) was observed by SRG/eROSITA as part of \nits all-sky survey between UTC 2020 Jan 16th and Jan 24th.�� Throughout \nthis period, the instrument scanned over the position with a cadence of 4hr.\n\nOn UTC Jan 20th 23:18:15 (820 seconds after the Fermi/GBM trigger) we \ndetected a bright and quickly fading X-ray source localized to\n\nRA(J2000) =���� 09:08:32.1 (137.13364 deg)\nDec(J2000) = -70:25:11���� (-70.43628 deg)\n\nwith an uncertainty of ~4\" arcsec radius. This position is consistent \nwith the Fermi/GBM (#26831) and IPN (#26856) localizations, suggesting \nthe source to be the X-ray afterglow of GRB200120A.\n\nAt the time of discovery, the source was detected with a count rate of \n44+/-2 cnt/s in the 0.2-10keV band, corresponding to a flux of approx. \n1x10E-10 erg/cm^2/s. The source was also found during the next scan 4hr \nlater. By then, it had faded to 2.8+/-0.5 cnt/s (approx. 6x10E-12 \nerg/cm^2/s). Further detections were obtained in the following three \nscans with count rates of ~1+/-0.3 cnt/s. Nothing was seen in the scans \nprior to the Fermi/GBM detection.",
