Example of the solar maximum brightness reconstruction for February 15, 2018, from LASCO/C2 data. The SMB line is shown in dashed black, while the HCS predicted from the PFSS reconstruction is shown in dashed red. The agreement is good at this period with a score of 84.6%, computed with a distance-based metric that accounts for the streamer thickness (see Poirier et al., 2021, for more details). The blue star indicates the connectivity point of Earth (ACE), with the closest distance to the SMB δ, displayed as a cyan arrow.
