TNG (3.5m), NOT (2.5m), OSN(1.5m), VLT (8.5m), Subaru, CFHT

Comments:

BAT: the burst has BAT high-redshift indicators
UVOT: no data products for this burst, because it is still in engineering mode.
VLT photometric reported redshift removed and replaced with TOUGH reported redshift. See references.
