Izzo (DARK/NBI), N. R. \nTanvir (U. Leicester), and G. Gomez Velarde (GRANTECAN) report:\n\nWe observed the XRT afterglow position (Osborne et al., GCN #30524) of \nGRB 210726A (Bernardini et al., GCN #30523), classified as a short GRB \n(Tohuvavohu, GCN #30535; Palmer et al., GCN #30536; Veres, GCN #30540) \nwith OSIRIS mounted on the 10.4m Gran Telescopio Canarias (Observatorio \nAstrof��isco Roque de Los Muchachos, La Palma, Canary Islands, Spain), \nunder mediocre conditions and at high airmass, starting July 26, \n21:21:31 UT, 2.041 h after the GRB. We obtained a sequence of 30, 30, \n60, 30 s images in r' for a total integration time of 150 s.\n\nWithin the XRT error circle, we do not detect any source down to r' > \n24.4 mag (AB magnitude), measured against a nearby PanSTARRS fiel star, \nat 0.088533 d (2.125 h) after the burst, in agreement with Kann et al., \nGCN #30543.\n\nThe possible host galaxy (Watson et al., GCN #30534, Kann et al., GCN \n#30543) is found at r' = 22.04 +/- 0.05 mag, again in agreement with \ndetections from the PanSTARRS and SDSS surveys.",
