----------------------------OVI doublet------------Ly a

The figure is the "first light" spectrum of the UVCS/Soho instrument. The observation is a 40 arcminute strip of the corona parallel to the east limb tangent and centered at about 3 solar radii from sun-center. The brightest part of each spectral line is believed to be from a streamer that is also being observed by the LASCO instrument. The HI Lyman-alpha line is from the redundant path of the UVCS OVI channel. The OVI doublet is from the direct path of the OVI channel. The low intensities away from the streamer indicate that the stray light levels are acceptable.
