The 2-m Liverpool Telescope with the RINGO3 polarimeter robotically followed up Swift GRB 140430A (Siegel et al., GCN 16190) at 20:35:40 UT (~2 min after the burst trigger).
We detect the optical afterglow at the UVOT position. In a coadded 3x10s SDSS-r image, we estimate a preliminary magnitude R = 18.4 +/- 0.1 at t_mid = 33.1 min since the Swift/BAT trigger time. The magnitude is calibrated against nearby USNO-B1 stars.
Observations are ongoing.
