Perez del Pulgar (UMA, Malaga), on behalf of a larger collaboration, report:
Following the detection of trigger 01709181970 by EP-WXT (Peng et al. GCNC 41045), the BOOTES-6/DPRT 0.6m robotic telescope at Boyden Observatory in Maselspoort (South Africa) responded to the alert on July 08, 22:29 UT (i.e. 6 min after detection and 2 min after notification). Within the reported EP-FXT error circle we find the star Gaia DR3 4587345820285675136 decreasing in brightness from 11.3 to 12.2 mag in clear filter and using Gaia DR3 Gmag magnitude as reference, during a ~1 hour time interval, confirming as due to a stellar flare.
We thank the staff at Boyden Observatory for their excellent support.
