POC: TBD With this present study, we want to observe equatorial coronal hole boundaries in order to find spectroscopic signatures of the physical processes which take place using simultaneously SUMER/EIS observations which will permit observations in spectral lines covering a large temperature range (from 40 000 K to a few million degrees).
