We study the various regions of the Sun, using high-resolution spectral observations from the Interface Region Imaging Spectrograph (IRIS). We observe the Quiet-Sun observation targeting the same region using different exposure times at different times and study the variation in the different parameters such as electron densities and filling factors using O IV line probing the transition region. We discuss the non-thermal width variations of Si IV line, as well. These observations will be able to provide better insights into interpreting upcoming new observations from Solar Orbiter SPICE spectrometer.
