We imaged the field of GRB 190821A detected by SWIFT (trigger 921722)with the T60 tele-operated telescope (D=60cm) located at Les MakesObservatory, Reunion Island, France. The observations started 790safter the GRB trigger. On the first image of 120s (Clear filter) wedetect the optical afterglow compatible with the position of XRT (Lienet al. GCNC 25427). start end R (sec) (sec) 790 910 18.4 +/-0.2 Further images are comming. Magnitudes were estimated with thenearby NOMAD1 stars and are not corrected for galactic dust extinction.
