Saccardi (GEPI, Observatoire de Paris) and B. Schneider (CEA Paris-Saclay), report on behalf of the Stargate Consortium: We observed the field of GRB 220427A (D'Ai et al., GCN 31960) using the ESO VLT UT3 (Melipal) equipped with the X-shooter spectrograph. In images taken with the acquisition camera 7.9 hr after the GRB we measure for the optical afterglow the following AB magnitudes (calibrated against 2 field stars from the SkyMapper catalogue): g' = 22.40 +/- 0.09 mag r' = 22.04 +/- 0.08 mag z' = 20.81 +/- 0.08 mag No useful spectroscopy could be secured. We acknowledge excellent support from the ESO observing staff in Paranal, in particular Jonathan Smoker and Rob van Holstein.
