We observed the position of the EP-WXT trigger 01709258851 with a Las Cumbres 1m telescope at Sutherland Observatory, South Africa, 50 mins after the Einstein Probe WXT trigger. We took 4x300s exposures in the broad optical w band.
We didn’t detect any uncataloged source within the EP-WXT error circle down to a limiting r-band mag of 21.5 mag.
