Perez del Pulgar (UMA, Malaga), on behalf of a larger collaboration, report: Following the detection of trigger 01709177124 by EP-WXT (Hu et al. GCNC [40568](https://gcn.nasa.gov/circulars/40568)), the BOOTES-6/DPRT 0.6m robotic telescope at Boyden Observatory in Maselspoort (South Africa) responded to the alert on May. 28, 17:17 UT (i.e. 2 min after detection and 32 min after notification). Within the reported EP-FXT error circle we find the star Gaia DR3 5778356748440163840 decreasing in brightness from 14.0 to 16.0 mag in clear filter and using Gaia DR3 Gmag magnitude as reference, during a ~3 hour time interval, confirming as due to a stellar flare. We thank the staff at Boyden Observatory for their excellent support.
