Perez del Pulgar (UMA, Malaga), on behalf of a larger collaboration, report:

Following the detection of the Oct 1 X-ray transient (dubbed GRB 241001A) by SVOM/ECLAIRS (SVOM team, GCNC 37665), the BOOTES-6/DPRT 0.6m robotic telescope at Boyden Observatory in Maselspoort (South Africa) observed the ECLAIRS X-ray transient location starting on Oct 1, 19:39 UT (~ 2.5 h after trigger). No new optical source is detected on the co-added images, covering a 15 arcmin radius around the ECLAIRS error box center down to 20.4 mag (clear filter).

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