Following the detection of trigger 01709259112 by EP-WXT (Tang et al. GCN 44099), both the 0.6m robotic telescopes BOOTES-5/JGU robotic telescope at San Pedro Martir Observatory (Mexico) and BOOTES-7 at San Pedro de Atacama (Chile) responded to the alert on March 24, 5:17 UT (i.e. 1 min after notification and 26 min after the trigger). Within the reported EP-FXT error circle we find the star SCOCENSUS 132-087992 decreasing 2.3, 1.9 and 1.6 mag in g, r and i filters during a 3.5 hours time interval, confirming EP-WXT trigger 01709259112 as due to a stellar flare.

We thank the staff at San Pedro de Atacama Celestial Observations and San Pedro Martir Observatory for their excellent support.
