Searching for Historical Solar and Auroral Activity Data
A Look into the Archive
The archive provides a timeline of historical solar and auroral activity data from 1932 to the present. The data is derived from the GFZ Potsdam Kp-index (1932-present) and the NOAA NCEI AA-index converted to Kpa (1868-1931).
The K-Index
The K-index, introduced by Julius Bartels in 1938, measures the intensity of geomagnetic storms on a scale from 0 to 9. It is widely used in space weather forecasting and research.
The Archive's Coverage
The archive covers a significant time period, starting from the year 1996. It contains data on the strongest geomagnetic storms observed since January 1932.
Conclusion
This archive is a valuable resource for scientists and researchers studying solar and auroral activity. The data it provides can shed light on long-term trends and help us better understand the impacts of geomagnetic storms on our planet and technology.
