E. Berger (Carnegie) and H. Yee (Toronto) report:
"We obtained a 180 sec image in I-band with the IMACS instrument on the
Magellan/Baade telescope on 2007 Apr 11.99 UT (3.55 hr after the burst).
We detect the afterglow with I=20.3 mag relative to the USNO-B star
located at RA=07:09:17.9453, DEC=+01:04:09.210 with I=17.8 mag."
