J. van Heerden (UFS, South Africa), A. Martin-Carrillo and L. Hanlon (UCD, Ireland), M. Gritsevich (Univ. of Helsinki), M. Jelinek (ASU-CAS), A. Kumar (ARIES) and C. J. Perez del Pulgar (UMA, Malaga), on behalf of a larger collaboration, report:

Following the detection of GRB 251014D by Swift/BAT (Klingler et al., GCNC 42272), the BOOTES-6/DPRT 0.6m robotic telescope at Boyden Observatory in Maselspoort (South Africa) responded to this event starting on Oct 14, 23:03 UT (~ 1.1 h after trigger) with 120s clear-filter images. No new source is detected within the Swift/XRT X-ray afterglow error box (Page et al., GCNC 42284) up to magnitude 18.3 using Gaia DR3 Gmag magnitude as reference. Further images were gathered, resulting on an upper limit of 21.0 (a coadd of 1200s on the aggregate, 1.6 post burst, at 23:30 UT).

We thank the staff at Boyden Observatory for their excellent support.
