report:
"The BOOTES-2 very wide field camera, located at the Estaci�n
Experimental de La Mayora (EELM-CSIC) in M�laga, observed the region of
the sky containing the SWIFT/BAT error box
for GRB 050421 (Barbier et al. GCN 3296) as part of its routine
observing schedule. A 30 s
exposure started at 04:12:00 UT (8 s after the onset of the 10 s long
burst), with the previous
frame starting at 04:11:00 UT. A limiting (unfiltered) magnitude of 9.0
is derived for any prompt
optical flash arising from this event."
