| Abstract: |
The 020410 event was detected with the BSAX-WFCs and its position disseminated within 4 hrs. In absence of BSAX-GRBM measurements, its GRB nature could be confirmed only weeks later through untriggered Konus-Wind γ-ray measurements. It turns out that GRB 020410 is an extreme example of a GRB: it lasted about 1600 s, it had a fluence that ranks in the top 5% of the BSAX sample and it was soft with a 2-10 to 50-300 keV fluence ratio fo 0.5. Two BSAX-NFI ToO observations revealed a slowly fading x-ray afterglow whose extrapolate 2-10 keV flux at 11h after the burst of 7.9 × 10-12 erg s-1 cm-2 is the highest of the BSAX sample. R-band optical data led to the (late) discovery of a relatively faint optical afterglow which shows evidence for reflaring. |
