GRB 021004

Position: 00 26 54.689 +18 55 41.3 (2000.0) D.W. Fox et al.
At 1206UT on 2002 October 4 the HETE spacecraft detected a long gamma ray burst. Less than 10 minutes later the Caltech-NRAO GRB collaboration identifed a 15th magnitude optical transient in Pisces. This transient was still visible at around 18th magnitude as night fell in the UK and a number of observers obtained images. To our knowledge these are the first UK detections of a GRB afterglow.

It seems that the redshift of this object is z=2.3 which works out to be around 11 to 12 billion light years away!
