  "body": "A. Bochenek and D. A. Perley (LJMU) report:\n \nWe observed the field of GRB250101a (Page et. al., GCN 38752) using the IO:O optical camera on the 2m robotic Liverpool Telescope. We obtained 6x200s exposures in the SDSS r’ filter starting at 2025-01-02 23:03:59 UT, approximately 1.4 days after the trigger. Three of the images had to be discarded due to autoguider issues.\n\nWe report a faint detection in the stacked images of r = 22.8 ± 0.2 mag, at a position consistent with the Swift/UVOT position (Page et. al., GCN 38752). The photometry was obtained using nearby PanSTARRS standards and was not corrected for extinction. The object continues to decline after re-brightening (Moskvitin et al., GCN 38765, Escudero-Coca et al., GCN 38769, Leonini et al., GCN 38771), consistent with the observations reported by Ghosh et al., GCN 38779 and Moskvitin et al., GCN 38780.\n",
