There is no optical transient with mlim=19.5(unfiltered) at Swift XRT ( #GCN 36057 158.851 deg, DEC = -35.747 (10:35:24.24 -35:44:49.20) ) and at GROND positions (Rau et al. GCN 36059 10:35:22.44 -35:44:08.2) ~23h after trigger time Observation started at 55deg altitude. Sun altitude was 11 deg. Reduction will be continued.
