P. O'Brien, N. Bannister, N. Tanvir (U. Leicester) report on behalf of
larger GRB collaboration:
We observed the field of GRB 080319A (trigger = 306754, Pagani et al.
GCN 7426) with the Liverpool Telescope (T_start = 32 min after the burst
event) and the Faulkes Telescope North (T_start = 525 min after the burst
event).
The optical counterpart reported by Cenko et al. (GCN 7429) and Malesani
et al. (GCN 7436), is clearly visible inside the XRT error circle
(Beardmore et al., GCN 7448) in our first images :
Telescope Filter DT_mean(min) Exposure(s) Mag Err
----------------------------------------------------------------------
LT r' 34.2 360 21.45 0.16
LT r' 43.3 600 21.94 0.40
FTN r' 542.3 1000 >20.61

Magnitudes were calibrated with respect to SDSS calibration's field (Cool
et al. GCN 7467).
