Following the detection of GRB 241128A by Swift (Brivio et al. GCN 38367), we triggered the 1.5m OSN telescope in Granada (Spain) starting on Nov 28, 18:19 UT (~2.1 hrs post burst) in R & I-bands. An uncatalogued object is detected within the XRT error circle (Page et al. GCNC 38368) with R=19.3+-0.1 mag, at coordinates RA(J2000) = 18:14:53.55, DEC(J2000) = +33:26:20.32, which we proposed as the GRB 241128A optical afterglow.
Spectroscopic observations are encouraged.
We thank the staff at OSN for their excellent support.
