The BeppoSAX New Transients and New Bursters


The lists below contain BeppoSAX discoveries of previously unknown transients and sources which reveal previously unknown bursting activity as advertized either via IAUC, papers and conference proceedings. The coordinates for the new BeppoSAX transient correspond to the first announcement. The column Instrument/Note reports which BeppoSAX instrument detected the new source or the new bursting activity.
