"We have observed the field of GRB 040825B
(GCN 2662) with the 2.2m(+CAFOS) Calar
Alto telescope on Aug 25.8443-25.8699 UT.
The observations were carried out in the
R-band (Texp = 4 x 300s) and cover the
entire GRB error box.
Visual comparison with the DSS-2 reveals
no variable source brighter than R~21."
