  GX 339-4 has been observed by BeppoSAX twice in spring 1997 as part of a
longer monitoring program. The source was close to the highest levels (50
mCrab) of the extended low state (as measured by the XTE ASM during the last 2
years). Its spectrum was quite hard, similar to the Exosat 1984 off state, but
40 times stronger. The source is detected up to more than 120 keV, enabling the
possibility to study its high energy spectrum
