 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 050215b (Barthelmy et al. 
 GCN 3024) as part of its routine observing schedule. 
 A 30 s exposure started at 02:33:05 UT (7 s prior to 
 the onset of the 10 s long burst), with the following 
 frame starting at 02:34:05 UT. Limiting (unfiltered) 
 magnitude of 10.0 is derived for any prompt optical 
 flash arising from this event.
