Comments

O VI broad profile at 21:54 UT at the top of the slit corresponding to the place in which the front of the CME crosses the slit first. Broad profiles in the knots suggesting bulk expansion (?). However broad profile may be due to the Doppler shift structure of the ejecta since the exposure time is long!!
