J. Gorosabel (IAA-CSIC,  Granada),  U. Carsenty  (DLR,  Berlin), P.  
Kubanek  (IAA-CSIC, Granada  &  U. of Valencia), G. Hahn  (DLR,  
Berlin), report on behalf of a larger collaboration:

"We have carried out R-band observations of the Swift GRB 101008A  
(Baumgartner et al., GCNC 11318, GCNC 11319) with the 1.23m Calar Alto  
telescope. The observations were carried out in R-band on October  
8.7957-8.8118 UT (2.38 -  2.76 hours post  trigger) under poor  
atmospheric conditions. We do not detect any optical source consistent  
with the XRT error circle (Baumgartner et al., GCNC 11319) down to a  
limiting magnitude of R=19.7 (3 sigma, calibrated against USNO-B1.0)".
