GCN 16477) with the\nVatican Advanced Technology Telescope and VATT4K CCD camera\non 2014 June 30.2757 (UT). The afterglow is well-detected in two 300s\nexposures through a SDSS-r filter.\n\nCalibrating from SDSS stars in the field we estimate the afterglow to be\nr=21.08 +/- 0.03 mag at 16.33 hours after the burst.\n\nCombining the brightness reported here and SDSS magnitudes estimated by\nMalesani et al. (GCN 16485) and Perley et al. (GCN 16491), the optical power\nlaw decay index is 1.7 between 7 and 16 hours after the burst.",
