This table contains information about observations (or attempted observations) by BeppoSAX (WFC and NFI) on GRBs. It is updated automatically in real-time. The most recent observation is listed first (reverse time order).
The 2 left-most columns (GRB) are the date and time of the start of the GRB.
The next 5 columns (Observation) come from the results of the various observations and analyses by the SAX WFC and NFI instrument teams. These columns contain: the Instrument that made the observation, the RA,Dec (J2000) location of the GRB, the error (arcmin radius, sys+stat) uncertainty in that location, the Flux of the detected source (in units of mCrab), a Comment describing the observation results, and if there is any Other related information (usually links). If a column's information is not available or is not applicable, then that entry is listed as "n/a".

X-ray burst or X-ray rich GB (GRB000416) On April 16 at 14:32:54 UT a burst was detected in WFC n.2 with a peak flux of about 2 Crab in the 2-26 keV range. The burst lasted about 25 s. Preliminary position is: R.A.(2000) 258.76 DEC(2000) -71.56 with an error radius of 4'. We name the source 1SAXJ1715.0-7134. A marginal detection of the burst in the GRBM (40-700 keV) woul to classify the event as an X-Ray rich GRB, although we could not exclude a type I X-ray burster on the basis of the WFC hardness ratio. A fast TOO observation was technically feasible but we could no t perform it because of budget reduction of BeppoSAX operations (see Bepp oSAX mail n. 00/06). |

A quick look analysis of the first five orbits of the MECS data at SOC shows only one object, previously unknown, inside the refined error circle of the WFC and located near the edge of the LMC. BeppoSAX will continue its observation and monitoring of this source up to a total observing time of 100 ksec. |

Preliminary analysis of the first three orbits of the MECS data at SOC shows a previously unknown source inside the WFC error circle. BeppoSAX is continuing its observation. |
| 99/07/04 | 17:30:20 | WFC | 184.79 | -3.80 | 7 | n/a | Refined coordinates. Due to the less-than-optimal attitude configuration the error radius is of about 7'. A follow-up with NFI is in progress. |

Unfortunately the attitude configuration at the time of the GRB does not allow to reconstruct the GRB position to better than about 1 degree radius. Due to the large error box, BeppoSAX is not going to observe this location with the NFI. |
| 99/05/10 | 08:49 | NFI | 204.605 | -80.490 | 1.5 | n/a | A BeppoSAX follow-up of GRB990510 started about 8 hr after the burst. Preliminary analysis of the first two orbits of the MECS data at SOC shows a previously unknown strong source in the center of the WFC error circle. Considering its strength, this X-ray source is likely the X-ray afterglow of GB990510. BeppoSAX is continuing its observation. |
| 99/05/10 | 08:49 | WFC | 204.5248 | -80.4925 | 3 | n/a | Final coordinates. GRB 990510 was detected by the GRBM and WFC of BeppoSAX on May 10, around 8:49 UT. A follow-on with NFI is being done. |

| 98/12/26 | 09:47 | NFI | 352.40 | -23.93 | 1.5 | n/a | Preliminary NFI coordinates. A follow-up with the NFI of GB981226 started yesterday Dec.26 around 20:34 UT. Preliminary analysis of the LECS and MECS detectors for the first 6 orbits shows a previously unknown source (a few x 10**-13 erg/cm2/s) within the WFC error box. At this stage of the observation we cannot yet establish whether the source is fading. The observation will finish tomorrow evening. |
| 98/12/26 | 09:47 | WFC | 352.433 | -23.942 | 8 | n/a | Preliminary WFC coordinates. A GRB (GB981226) was detected by the GRBM and WFC of BeppoSAX on Dec.26, around 9:47 UT. The error radius is about 8', including a systematic error due a less-than-optimal attitude configuration. A follow-on with NFI is being planned. |
