Presented is a list of voltages (electric potential differences) measured during magnetic storms on grounded long lines in the United States and Canada between 1891 and 1940. The sources for the list are published papers, technical documents, and newspapers. Each entry consists of the maximum voltage measured for each storm on a specified line connecting two ground points, nominally, between A "and" B. However, if a specific polarity is available, for example, the positive voltage from point A to point B, then the maximum voltage for the indicated polarity is listed, that is, positive A "to" B; conversely, for the opposite polarity, that is, from point B to point A, then the maximum voltage for the indicated polarity...

Anomaly lists are presented documenting operational interference to electricity power grids and communication networks in the United States and Canada during magnetic storms. Four of the anomaly lists apply for magnetic storms that occurred in March 1989, August 1972, March 1940, and for various storms 1946-2000; yet another list consists of statistical values summarizing geomagnetically induced current data for 1969-1972. The lists are compiled from source published papers, technical documents, and research papers. These sources generally include brief descriptions of each anomaly and attribution to a particular magnetic storm. Other information, when given, includes utility company name, facility name, start date...
