J. van Heerden (UFS, South Africa), A. Martin-Carrillo and L. Hanlon (UCD, Ireland) and C. J. Perez del Pulgar (UMA, Malaga), on behalf of a larger collaboration, report:

Following the detection of GRB 240102A by Swift (Gropp et al. GCNC 35461), the BOOTES-6/DPRT 0.6m robotic telescope at Boyden Observatory in Maselspoort (South Africa) observed the GRB location starting on Jan. 2, 18:41 UT (~ 1.1 hours after trigger) in different optical bands. No new optical source is detected on the co-added images (2 x 60 s, clear-filter) within the Swift/XRT error box down to 20.2 mag. Further imaging is ongoing.

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