Streamer HI Ly-α Line Profiles During the Spartan 201-05/SOHO Coordinated Observations
Abstract
We present H I Lyalpha observations of coronal streamers obtained by UVCS/SOHO during the coordinated observations with UVCS/Spartan on 1 3 November 1998. Two different streamer regions were observed, one relatively stable above the Northeast limb, and a postCME streamer complex above the Southwest limb. H~I Lyalpha profiles and intensities were measured at ~1.5 and 2 Ro in the NE streamer and its boundary regions, and also at heights ranging from 1.5 to 2.5 Ro in the SW streamer complex. We analyze integrated intensities and line widths in each streamer structure.
