Groot (Radboud/UCT/SAAO) report on behalf of the\nMeerLICHT consortium:\n\nWe observed the Swift/BAT-GUANO localisation of GRB 221115B (DeLaunay et\nal., GCN 32941) with the 0.6m wide-field MeerLICHT optical telescope\nsituated in Sutherland, South Africa, obtaining 2x300s observations in the\nq-band (roughly g+r) fully encompassing the 3' error box. Observations\nbegan at 21:21:30 UT on 2022 November 16, 1.48 days post-trigger.\n\nEmploying our transient detection pipeline along with an archival reference\nimage, we detect no new transients within the GUANO error box down to a\n5-sigma transient limiting magnitude of q > 20.80. Our new images had\nfull-frame 5-sigma limiting magnitudes of q = 22.10 and q = 22.18, while\nour archival reference image had a limiting magnitude of q = 21.10. All\nmagnitudes are in the AB system.\n\nMeerLICHT is built and run by a consortium consisting of Radboud\nUniversity, the University of Cape Town, the South African Astronomical\nObservatory, the University of Oxford, the University of Manchester and the\nUniversity of Amsterdam.",
