Abstract
We analyze temporal variations in the intensities and the Doppler shifts of He i 584.33 Å (chromosphere), Ov 629.73 Å (transition region), and
Mg ix 368.07 Å (corona) measured in and above chromospheric network near disk center with the Coronal Diagnostic Spectrometer (CDS)
onboard the Solar and Heliospheric Observatory (SOHO). There is
