report:
"Following the detection by Swift of the GRB 070419B
(Parson et al. GCNC 6305), we have obtained R & I -band
images at the 0.6m B&C telescope at the Mt. John Observatory
on Lake Tekapo, New Zealand. They were taken starting
on Apr 19.537 UT (i.e. 2.17 hr post-burst).
The single frames (360s in R) reveal a point-like source
with R ~ 20 consistent with the Swift/XRT error box which
is not present in the DSS-2 red. Preliminary coordinates
(+/- 1") yield:
AR(2000): 21:02:49.80
Dec(2000): -31:15:49.23
More details will be given on forthcoming GCN Circular."
