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.
