For each Carrington rotation, there are two coronal synoptic maps of the sun in each of 3 Fe lines (171A, 195A, 284A) and in He (304A) These maps are from the Extreme Ultraviolet Imaging Telescope
We report on the properties of halo coronal mass ejections (HCMEs) in solar cycles 23 and 24. We compare the HCME properties between the corresponding phases (rise, maximum, and...
The Coronal Diagnostics Spectrometer (CDS) onboard SOHO studies the emission line characteristics in the extreme ultraviolet (EUV) of the Sun. CDS observes the Sun's coronal properties and its interac
