GCN 37648) possibly associated with GRB240930a (Fermi GBM team, GCN 37633) using the IO:O optical camera on the 2m robotic Liverpool Telescope. We obtained 5x120s exposures with the SDSS-r filter starting at 2024-10-01 20:37:49 UT, approximately 27.3 hours after the EP trigger.\n \nThe images were stacked and a reference image of the field from Pan-STARRS was subtracted using PSF matching with the help of PSFEx. No uncatalogued optical source was detected within the 90% confidence 10 arcsec EP/FXT error-circle. The 3-sigma limiting magnitude on the subtracted image is r > 22.16 mag.",
