Other Burst Info:
Redshift:~2.8 (UVOT: photometric)Host Galaxy:
2.106 (VLT: absorption)
Other Observatory Detections:
KAIT, Lick (1.0m), PROMPT (16"), ISON-NM Observatory (0.45m), MPI/ESO (2.2m), Fermi (GBM), NOT, VLT
Comments:
UVOT: The non-detection in the UV filters suggests a photometric redshift of z~2.8
