Following the detection of trigger 01709195487 by EP-WXT (Liang et al. GCN 41173), the 0.6m robotic telescopes BOOTES-7 at San Pedro de Atacama (Chile) responded to the alert on July 27, 07:40 UT (i.e. 2 min after notification and 6 min after the detection). Using SDSS g filter and ATLAS REFCAT2 gmag as a reference, we measure an initial magnitude of 12.2 +/- 0.1. Later, on July 27, 23:55 UT (16.25 hours after BOOTES-7 images) the BOOTES-6/DPRT 0.6m robotic telescope at Boyden Observatory in Maselspoort (South Africa) covered the same region, measuring the same source in the same filter with a magnitude of 13.0 +/- 0.1, confirming the EP X-ray trigger due to a stellar flare.
We thank the staff at San Pedro de Atacama Celestial Observations and Boyden Observatory for their excellent support.
