Filippenko (UCB) report on behalf of the KAIT GRB team:\n\n\nThe 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at\n\nLick Observatory, observed the field of EP250828a (Liu et al.,\n\nGCN 41574) starting at 09:30, Aug 28 UT, about 1.97 hours after\n\nthe burst. A set of clear (roughly R) filter images were obtained.\n\nIn our coadd image, we did not detect the reported afterglow\n\n(Taguchi et al., GCN 41582; Yao et al., GCN 41583; Fu et al., GCN\n\n41584) down to a limiting mag of 20.5 mag (Vega) at a mid-time of\n\n2.67 hours after the burst.\n",
