History

Historical Context

The Carrington Event, occurring on September 1-2, 1859, was the most intense geomagnetic storm recorded, resulting from a coronal mass ejection. This event produced spectacular auroras visible worldwide, even in tropical regions. The U.S. Weather Bureau, established in 1870, evolved into NOAA, which now utilizes advanced technology to monitor solar activity and predict auroras, enhancing public interest in space weather and astronomy.
