Following the detection of trigger 01709322206 by EP-WXT (Wang et al. GCN 46132Loading...
 
 ), the 0.6m robotic telescopes BOOTES-5/JGU robotic telescope at San Pedro Martir Observatory (Mexico) responded to the alert on Nov 3, 02:37 UT (i.e. 11 min after the detection). Within the reported EP-FXT error circle we find the star HG 7-33 decreasing 0.16 mag in brightness (clear filter) during a 40 min time interval, confirming the EP X-ray trigger due to a stellar flare.

We would like to thank the staff at San Pedro Martir Observatory for their excellent support.
