We observed the field of GRB 070419A (GCN 6302) with MINT
on the 2.0-m NAYUTA telescope at Nishi-Harima Astronomical
Observatory, Japan. We took images for a total of 100 sec in
R-band filter on 2007 Apr 19 10:55 UT (56 minutes after the burst).
The afterglow was detected with 20.1 mag relative to USNO-B stars.
