Cockeram (LJMU) report:\n\nWe obtained further observations of the afterglow of GRB 190829A \n(Dichiara et al., GCN 25552; Lesage et al., GCN 25575; Xu et al., GCN \n25555) with the IO:O imager on the 2m robotic Liverpool Telescope. \nObservations were conducted on 2019-09-02 (03:33-04:03 UT) and \n2019-09-03 (02:46-03:36 UT).\n\nIn all three filters, the optical afterglow has slowed its decay from \nits previous power-law decline (GCN 25597), with little additional \nevolution in flux over the past 48 hours.  There is tentative evidence \nfor rebrightening in the i-band.  We interpret this as the beginning of \nthe rise of an associated supernova, but this still requires \nspectroscopic confirmation.\n\nAdditional i-band photometry (all subtracted versus PS1 reference \nimaging, with times in days referenced to the Swift trigger) is as follows:\n\n  t-t0    filt   mag       unc\n  ------  ----   -----     ----\n  3.3193  i    = 21.69 +/- 0.12\n  4.2889  i    = 21.45 +/- 0.12\n\n\n\n\n\n\n\n\n\n\n\n\nDisclaimerNone",
