Research on Solar Corona during Total Solar Eclipses

Total solar eclipse observations have played a pivotal role in unveiling numerous secrets of the solar corona.From its initial identification in the 17th century to groundbreaking revelations about its million-degree temperatures in later centuries, eclipses have continued to provide key insights into the corona's dynamics and its dependence on solar activity cycles.Despite advancements in instrumentation and theoretical models, eclipses remain unparalleled opportunities for coronal research.Notably, the region of the corona most effectively observed from the ground during these events is inaccessible to any current space-based coronagraphs.Our team have yet organized 7 scientific expeditions to observe total solar eclipses for the last 26 years.In the current paper we share our experience on the obtained research and conducted experiments underlining the point of continuing such observations today.
