of larger collaboration, reports
We observed the field of GRB 121017A (Grupe et al., GCN Circ. 13875)
with the 1-m Zeiss-1000 telescope of SAO RAS
in Rc band. The weather conditions were good, airmass = 5 - 6, seeing
= 2.6". Observations were started since 9.5 minutes
after the BAT trigger, middle time t-t0 = 0.01407 days.
We do not detect any object in the XRT error circle down to a limiting
magnitude 18.8 as well as Jelínek et al. (GCN Circ. 13876).
