These pictures show the discovery observation of the X-ray afterglow
from the famous Gamma Ray Burst GRB970228 together with a follow-up observation
carried out three days after the event. By the time of the second observation
the X-ray afterglow dimmed below the BeppoSAX detectability threshold.
The plot to the right shows the rapid decay of the X-ray flux
coming from a different Gamma Ray Burst event which occurred on May 8 1997.
The X-ray intensity from this source decreased almost one
million times in less than one week.
