HETE-2 triggered 166 events from SGR1900+14 and SGR1806-20 in summer periods from June 18 2001 to September 8 2004. Among these events, 6 events were localized to SGR1900+14 and 53 events to SGR1806-20. We performed the energy spectral analyses of bursts from SGR1900+14 and SGR1806-20 using the data of the WXM and FREGATE onboard HETE-2. We find that the energy spectra of SGR1900+14 and SGR1806-20 are well described by a sum of two blackbody models with temperatures of ˜4keV and ˜11keV.
