(Two right images) XRF 020427
Event type	X-ray flash
Date	10 June 2002
Instrument	Hubble Space Telescope (HST)
Redshift	~3.5
Other designations	GRB 020427, XRF 020427

XRF 020427 was a X-ray flash. It was observed with the Hubble Space Telescope (HST) on the 10th of June 2002 in rather poor seeing conditions. ^{[1] [2]} The afterglow of this XRF resembles the properties of some gamma-ray bursts (GRB). This is probably due to an inefficient shock from XRF 020427. ^[3] This further strengthens the connection of X-ray burst to GRBs. ^[4]
