report:
The BOOTES-2 very wide field camera, located at the Estaci�n
Experimental de La Mayora (EELM-CSIC) in M�laga, observed
the two regions of the sky containing the SWIFT/BAT error
boxes for GRB 041224 (Barthelmy et al. GCN 2908) and GRB
041226 (Krimm et al. GCN 2914) as part of its routine
observing schedule. For GRB 041224 a 30 s exposure started
at 20:21:00 UT (3 s after the onset of the 50 s long burst),
with the following frame starting at 20:22:00 UT. For GRB
041226 the 30 s exposure started at 20:34:00 (19 s prior to
the onset of the 20 s main emission peak). Limiting (unfiltered)
magnitudes of 8.5 and 7.0 respectively (due to the presence
of the full moon) are derived for any promt optical flash
arising from either of these two events.
