In June 2000 the SOHO and Ulysses satellites reached the quadrature configuration with respect to the Sun. On this occasion the JOP 112 was run, with the aim of studying the coronal and solar wind physical parameters, with particular attention to the element composition. In this paper we present preliminary results from SOHO/SUMER and CDS/NIS data. The two instruments were pointed off-limb and observed the lower solar corona in the Ulysses direction (-58.2 deg in the S-E quadrant). During the period of observations (12-17 June) the observed corona was filled with streamers. From each instrument the electron density, temperature and element composition of the studied areas have been derived. A comparison of the results from the two instruments is then presented.
