(Harvard), and A. Rest (NOAO) report:

"We obtained a 60 sec image in r-band with the LDSS3 instrument on the 
Magellan/Clay telescope on 2007 Apr 12.03 UT (4.57 hr after the burst). We 
detect the afterglow with r=20.8 mag relative to the USNO-B star located 
at RA=07:09:17.9453, DEC=+01:04:09.210 with R=17.6 mag."
