Thoene (HETH/IAA-CSIC) report:\n\nWe observed the  GRB 190829A (Fermi GBM team, GCN 25551; Dichiara et al.,\nGCN 25552) with the 2-m Liverpool Telescope located in La Palma, Spain.\nThe observation started at 05:29:50 UT on August 30, 2019 (t-t0 = 9.55 hours).\nWe obtained 5x60 seconds exposures in r'. We clearly detected the optical\nafterglow inside the SWIFT error circle given of Evans et al. (GCN 25567).\nWe measure the following magnitude\n\nr' = 19.79 +- 0.10 mag,\n\nMagnitudes were derived from against comparison stars from the SDSS catalogue\nand are in the AB system.",
