J. Japelj, D. Kopac (U. Ljubljana) and C. Guidorzi (U. Ferrara) report on
behalf of a larger collaboration:
The 2-m Faulkes Telescope North automatically began observing GRB 120224A
(Saxton et al., GCN 12980), starting at 04:44:40 UT on 2012 February 24.
We do not detect any optical counterpart inside the enhanced Swift-XRT
error circle (Osborne et al., GCN 12981) down to the following limiting
magnitudes:
Mid time from Exp Filter Mag limit
trigger (min) (sec)
-------------------------------------------
44.5 600 R > 19.3
39.3 480 i' > 18.6
-------------------------------------------
The magnitudes are calibrated against nearby USNO-B1.0 stars.
