J. Gorosabel (IAA-CSIC/UPV-EHU), S. Hellmich (DLR), A. de Ugarte Postigo (IAA-CSIC), S. Mottola (DLR), C. Thoene (IAA-CSIC), report on behalf of a larger collaboration:

We observed the field of GRB 141220A with the 1.23m CAHA in the I-band starting  ~8 min post burst. A bright afterglow is detected at RA(J2000)=13:00:15.76, DEC(J2000)=32:08:46:4 (+/-0.8"). We note an important discrepancy with the initial position reported by Swift.
