The observations were started on April 19, at 03:55 UTC (19 hours after the burst) and stopped at 05:35 UTC. Four unfiltered 600 seconds images were taken. We do not detect any new object with respect to POSSII F/USNO-B1.0 inside the BAT error circle. Upper limit for the observations is > 20.5 mag (3UL). Quoted upper limit has been derived using POSSII F and USNO-B1.0 field stars as reference. Quoted upper limit has been derived using POSSII F and USNO-B1.0 field stars as reference.
