Study 000225: ACRONYM: madj_ech_small The study is designed to take a small (24"x512") raster observations with 2" x 512" slit of the quiet Sun, coronal hole boundaries both equatorial and polar or an off-limb region above coronal holes. The new study is covering a large number of spectral lines some covered with large spectral windows. The selection is based on the results of already ongoing study. TARGET : Quiet Sun, Coronal hole boundaries or off-limb region EXPOSURE TIME : 60s SLIT : 2" FOV : 24"x512" SPECTRAL WIND.: various size spectral windows DATA COMP. : lossless Repetition : to be repeated to fill 5 hours of observations. POINTING: Target: quiet Sun, coronal hole boundaries both polar and equatorial and off-limb region of the Sun (west limb). If a target of opportunity is available such as a filament or a prominence showing signs of forthcoming activation, this study could be used. The study requires compensation for the solar rotation i.e. we would like to follow one and the same region from the Sun. WARNING: None
