Abstract
We report on initial observations of coronal hole structure and evolution by the Coronal Diagnostic Spectrometer (CDS) instrument on board the Solar and Heliospheric Observatory (SOHO). The date show that there is coronal actiVity on time scales of tens of minutes, manifested as brightenings at chromospheric network cell junctions in eitreme ultraviolet (EUV) wavelengths. There are also significant differences in structure seen in different wavelengths in coronal holes. Finally, we show coronal hole EUY spectra and compare them to quiet-Sun spectra, also taken by CDS.
