Composite solar images of an equatorial streamer observed from August 30 to September 2, 1996 at east limb. The disk is imaged with EIT/SOHO in the Fe XII 195 Å line. The limb images are obtained with the LASCO/SOHO C2 coronagraph. The slit (IFOV) of UVCS is superposed to the coronal images in HI Lyα 1216 Å line (left panel) and in OVI 1032 Å line (central panel). Right panel: intensity profiles along the slit at 1.89 R_⊙ of HI Lyα 1216 Å line (black line) and of OVI 1032 Å line (blue line). The core dimming in OVI spectral line emission is evident.
