C. Guidorzi (U. Ferrara), R. Smith (LJMU), A. Gomboc (U. Nova Gorica), C.J. Mottram, I.A. Steele (LJMU) report:
The 2-m robotic Liverpool Telescope automatically started observing with the MOPTOP polarimeter GRB 240929A detected by Fermi, INTEGRAL, SVOM, GRBAlpha (Fermi GBM team, GCN 37627; Mereghetti et al. GCN 37630; SVOM team, GCN 37650; Dafcikova et al., GCN 37657) at 19:54:06 UT, that is 242 s after the Fermi/GBM trigger time. In a 64x4s stacked frame in the MOP-R filter from 242 to 405 s since the Fermi/GBM trigger time, we do not find any uncatalogued object down to R>19.5 mag within the INTEGRAL error circle (Mereghetti et al.), as calibrated against Pan-STARRS catalog field stars.
