Japelj (U. Amsterdam), A. Rossi (INAF-OAS), D. B. Malesani(DTU Space), K. E. Heintz (Univ. Iceland), G. Pugliese, L. Kaper(U. Amsterdam) report on behalf of the Stargate collaboration:We observed the field of GRB 190531B (Fermi GBM team, GCN 24695;Kunzweiler et al., GCN 24696; Axelsson et al., GCN 24701) with the ESO VLTUT2 (Kueyen), using the X-shooter acquisition camera. A 3x30 s exposurewith the SDSS r filter was taken at approximate time 2019 June 1.39 UT(0.55 days after GRB).We do not detect any new object within the error region of the detectedX-ray afterglow (D'Avanzo et al., GCN 24706), down to a 3-sigmalimiting magnitude r > 23 AB (calibrated against nearby star at positionRA=01:37:12.696, Dec=-41:57:36.702). The closest source to the XRT errorcircle is at RA=01:37:11.37, Dec=-41:57:30.73, which is 3.1 arcsec awayfrom the XRT location, and is thus unlikely to be related to the GRB.We acknowledge excellent support from the observing team in Paranal,in particular Alex Correa, Florian Rodler and Pascale Hibon.
