Report: following the detection of GRB 971227 by BeppoSAX, R-band
images were obtained by Y. Aguilar and R. Kohley (Sternwarte der 
Universitat, Bonn) with the 2.2-m CAHA telescope (+CAFOS) at the German-
Spanish Calar Alto Observatory, on Dec 27.91, Dec 28.16 and Dec 29.12 .
A careful visual inspection of the three frames reveals no variable object 
(by more than 0.5 mag) above a R = 21.5 limiting magnitude within the entire 
BeppoSAX WFC error box (8' radius). Further observations are in progress.
