GCN 525, Kippen et al. GCN 526) with the wide-field CCD of BOOTES-1 on Jan 27.89 UT (22-h after the GRB, 5-min exposure time) and with the narrow-field CCD attached to the 0.3-m telescope on Jan 28.89 UT (46-h after the event, 10-min exposure time). Limiting magnitudes of the unfiltered images are about 11 and 19 respectively. None of them reveals any new (or strongly variable source) when comparing with the Digital Sky Survey, in agreement with the results obtained by Axelrod et al. (GCN 527). The two images are posted at http://www.laeff.esa.es/~ajct/GRBs/GRB000126." This message is quotable.
