With MeerLICHT's 2.7 square degree\nfield-of-view sampled at 0.56\"/pix, a set of 24 fields covered the 95%\narea. Each field was observed in a set of u, q (440-720nm), i bands in\none-minute exposures per filter, starting at 23:11 UT 2019-08-14, and\ncontinued throughout the night until dawn at 04:19 UT 2019-08-15. Each\nfield was covered at least twice with a 2-hour time separation. The\nmajority was covered a third time before dawn. Sky conditions were\nphotometric, with a seeing around 2.5\" in q-band. Limiting magnitudes\n(5-sigma point-source) were 18.5 mag (u), 19.7 mag (q) and 19.1 mag\n(i) in 60s exposures affected by full-moon conditions. Data processing \nis ongoing and results will be reported when they become available. Monitoring of the updated skymap [2] will continue over the coming \nnights.\"\n\nThe MeerLICHT telescope [3] is designed, built and operated by the\nMeerLICHT consortium consisting of Radboud University, the University\nof Cape Town, the Univerity of Oxford, the South African Astronomical\nObservatory, the University of Manchester and the University of\nAmsterdam, with support from the Netherlands Research School for\nAstronomy NOVA, the Netherlands Organisation for Scientific Research\nNWO, the KU Leuven and the South African Radio Astronomical\nObservatory.\n\nReferences:\n[1] LVC Collaboration, GCN Circ. 25324\n[2] LVC Collaboration, GCN Circ. 25333 \n[3] Bloemen et al., 2016, SPIE.9906E..64B",
