| Event type | X-ray flash |
|---|---|
| Duration | 1500 seconds |
| Instrument | BeppoSAX |
| Redshift | 3.5 |
| Notable features | One of the longest X-ray flashes to date |
XRF 011030 was a long X-ray flash (XRF) that lasted for about 1500 seconds making it one of the longest X-ray flash observed by BeppoSAX to date. It lies at a distance less than z=3.5.[1] Observations of XRF 011030 are consistent with a thick shelled fireball expanding on a stellar wind environment or a jetted fireball in an interstellar medium (ISM).[2] But it can also be explained by both a stellar wind environment and a interstellar medium.[3] Because of the short distance from earth, it is likely not a gamma-ray burst (GRB).[1]
It was observed by BeppoSAX about 1300 seconds after the burst.[3]
