"The BOOTES-1 and BOOTES-2 very wide field cameras, located at INTA-
CEDEA (Huelva, Spain) and EELM-CSIC (Malaga, Spain) respectively, and
distant 200 km each other, observed the region of the sky containing the
SWIFT/BAT error box for GRB 050525 (Band et al. GCN 3466, Markwardt
et al. GCN 3467, Cummings et al. GCN 3469) as part of their routine
observing schedules. 30 s exposures started simultaneously at 00:03:00 UT
(7 s after the onset of the 10 s long burst), with the following frame
starting
at 00:04:00 UT (i.e. covering the late part of the event). A limiting
(unfiltered)
magnitude of 9.0 is derived for any prompt optical flash arising from this
particular GRB. Images are posted at:
