Other Burst Info:
Redshift:4.5 (MPI/ESO: photometric)Host Galaxy:
4.6667 (VLT: absorption)
4.7 (Gemini South: absorption)
Palomar: potential (lowish redshift) host candidate.Other Observatory Detections:
UVOT: The fading observed suggests that this is the afterglow of GRB 100219A superimposed on the host galaxy candidate (GCN 10433).
