		| Abstract: | 
		We tried to do a comparison of Ca II K (393.3 nm) filtergrams obtained at the Vacuum Tower Telescope on Tenerife with spectra in the line Si IV 139.4 nm obtained simultaneously with the SUMER telescope on the SOHO-spacecraft. Some bright features can be well identified in both observations. We compare temporal changes of the brightness for these common features. |
