Young (QUB), I. Manulis (Weizmann), report:\n\n\nWe observed the field of GRB 210211A (Fermi GBM Team, GCN Circ. 29470; Troja et al., GCN Circ. 29472) under the advanced extended Public ESO \nSpectroscopic Survey for Transient Objects (ePESSTO+; see Smartt et al. 2015, A&A, 579, 40 http://www.pessto.org <http://www.pessto.org/> ). The observations were performed \non the ESO New Technology Telescope at La Silla with the EFOSC2 instrument in imaging mode on 2021-02-16 between 08:01:05 UT and 08:42:23 UT \n(i.e. about 4.99 days from the burst). The observations were carried out with the R filter under a seeing of about 1.9\". \n\nThe optical afterglow (D'Avanzo et al., GCN Circ. 29474; Lipunov et al. GCN Circ. 29477; Kuin et al., GCN Circ. 29485) is not detected down to a 3sigma \nlimiting magnitude of R ~ 24.3 (Vega; based on preliminary photometry calibrated against the USNO B1 catalogue).",
