We observed the position of GRB 141015A (Troja et al. GCN Circ. 16909) with the 1-m McDonald telescope (Fort Davis, US), a member of the Las Cumbres Observatory network. Observations started on October 15 at 09:51:01 UT, i.e., 38 minutes after the GRB trigger time (GCN Circ. 16909) and were done with the g', r' and i' filters.
We did not find a new source within the enhanced XRT error circle (Evans et al. GCN Circ. 16913) down to the following limits:
Mid time from Total Exp Filter Magnitude
trigger (min) (s)
-----------------------------------------------------------
54.4 600 r' > 19.6
59.2 600 i' > 18.7
-----------------------------------------------------------
Magnitudes are calibrated against nearby USNO-B1 stars.
