Observations of GRB X-ray afterglows with SODART/SRG

Despite recent progress with the detection of afterglows of Gamma Ray Burst s (GRBs), the nature of these events is unknown. However, important clues t o understanding what the GRBs are, may very well be found by studying the X -ray afterglows. The combination on SRG of the MOXE all-sky monitor for det ecting GRBs, and the powerful pointed SODART telescopes will be a unique to ol for studying the long-term behavior of GRB afterglows. It is shown that SODART will be able to follow the temporal and spectral development of a GR B similar to the now famous GRB 970228 event for well over 20 days in order to provide constraints on theoretical models.
