FEE CTU Prague) We observed the field of the Swift GRB 140108A (Racusin et al., GCNC 15699) with the 0.5m telescope D50 and 0.25m telescope BART in Ondrejov (Czech Republic), starting at 17:19:20 UT, i.e. 36s after the trigger. We detect a new variable and uncatalogued object within the XRT coordinates 21:40:26.813 +58:44:40.17 (J2000) +-1". Preliminary photometry provides brightness of R~18.0 300s after the GRB trigger.
