Hudec (ASU CAS Ondrejov) report:\n\nWe observed the position of the Einstein Probe WXT trigger 01709322274\n(T0 = 2026-11-06 21:28:37 UT; RA, Dec = 46.972, +24.975, err 3.1 arcmin)\nwith the D50 telescope of the Astronomical Institute Ondrejov, near\nPrague, Czech Republic. We obtained 10 unfiltered images, each a sum of\n100x1.1 s exposures, between 21:43:37 and 22:02:13 UT (T0+15 min to\nT0+34 min). Observations are continuing.\n\nWe detect a fading high proper motion M dwarf 1.5 arcmin from the WXT\nposition, at\n\nRA, Dec = 03:07:47.32, +24:57:51.9 \n\n\nThe star is well detected in single images and fades steadily throughout\nour sequence, from 13.15 to 13.27 mag (0.44 +/- 0.04 mag/h, residual rms\n0.013 mag) in RC. Field stars of similar brightness are constant to within\n0.01-0.02 mag. No other M-dwarf-coloured star in our field varies\nsignificantly, and this star is the brightest and highest proper motion\nM dwarf in the field.\n\nPhotometry is unfiltered, calibrated against ATLAS-RefCat2\nstars, and not corrected for Galactic extinction.
