Scientific American magazine reports new data suggest the 1921 ‘New York Railroad Storm’ could have surpassed the intensity of the famous Carrington Event of 1859<\/p>\n

In a paper published in the journal Space Weather,\u00a0Jeffrey Love<\/strong>\u00a0of the U.S. Geological Survey and his colleagues reexamined the intensity of the 1921 event, known as the New York Railroad Storm, in greater detail than ever before. Although different measures of intensity exist, geomagnetic storms are often rated on an index called disturbance storm time (Dst)\u2014a way of gauging global magnetic activity by averaging out values for the strength of Earth\u2019s magnetic field measured at multiple locations. Our planet\u2019s baseline Dst level is about \u201320 nanoteslas (nT), with a \u201csuperstorm\u201d condition defined as occurring when levels fall below \u2013250 nT.<\/p>\n

Studies of the very limited magnetic data from the Carrington Event peg its intensity at anywhere from \u2013850 to \u20131,050 nT. According to Love\u2019s study, the 1921 storm, however, came in at about \u2013907 nT. \u201cThe 1921 storm could have been more intense than the 1859 storm,\u201d Love says. \u201cPrior to our paper, [the 1921 storm] was understood to be intense, but how intense wasn\u2019t really clear.\u201d<\/p>\n
