To verify such phenomena, it is important to evaluate them using multiple nuclides from different archives. The cosmic ray event in 993\u2013994 Common Era (CE) has already been confirmed with 14C and 10Be data, which show rapid increases in the concentrations. However, the 10Be data were obtained from the Greenland ice cores in the Northern Hemisphere. To investigate the extent of the 10Be increase in the Southern Hemisphere, we measured quasi\u2010annual 10Be concentrations between 980 and 1,011 CE in the Antarctic Dome Fuji ice core. We observed a ~50% increase in 10Be concentration around 994 CE, consistent with the Greenland data. Increases in 10Be concentrations in both hemispheres support a solar origin of the 994\u2010CE event. In addition, we propose a method of evaluating the so\u2010called \u201csystem effect\u201d for 10Be deposition by extracting common components from 10Be and Na+ data.",
