Guessoum (AUS), on behalf of the GRANDMA collaboration:\n\nWe observed the field of GRB 241217A, detected by SVOM/ECLAIRs (GCN 38594) using TAROT/TRE. Observations (unfiltered) began at 2024-12-17T17:22:00UTC, 19 min after T0 and continued up to 45 min after T0.\n\nWe did not detect any optical afterglow candidate in our stacked images within a 5-sigma upper limit of r > 18.1 (AB magnitude, calibrated with PanSTARRS).\n\nAll the data have been reduced by a single data processing pipeline, STDPipe (Karpov et al., 2022). \n\nGRANDMA is a worldwide telescope network (grandma.ijclab.in2p3.fr) devoted to the observation of transients in the context of multi-messenger astrophysics (Antier et al. 2020 MNRAS 497, 5518).",
