GCNC 8980)\nwith the 1.5m OSN telescope (Granada, Spain) starting on  22:29 UT\n(13.4 hours after the burst). Our I-band images show that the optical\nafterglow reported by Chornock et al. (GCNC 8979) is still bright.\nPreliminary photometry yields I=17.7+/- 0.3. This would imply that the\nplateau phase reported by Perley et al. (GCN 8985) is still ongoing,\nhalf a day later.\n\nFurther observations are encouraged",
