Kodaikanal Observatory's Century-Long Data Offers Insights into the Sun's Future

Astronomers have developed a method to reconstruct the Sun's past polar magnetic behavior using over a century of historical solar images from the Kodaikanal Solar Observatory. This research, led by Dibya Kirti Mishra and collaborators, reveals crucial insights into solar cycles and magnetic fields, which are essential for predicting future solar activity. The findings highlight the importance of historical data in understanding solar magnetism and its implications for Earth, including potential impacts on satellites and power grids. The complete dataset is publicly available for further research.
