North American electricity power-grid and communication-network anomalies for several magnetic storms
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 and time, end date and time. None of the sources include specific locations (latitude and longitude) of the anomalies. In the lists given here, the latitude and longitude of each anomaly are obtained either from a list of power-grid facilities available from the Department of Homeland Security, by estimating facility locations from digitized and georeferenced paper maps, or from internet-based maps.

Mapping a magnetic superstorm: March 1989 geoelectric hazards and impacts on United States power systems
A study is made of the relationships between geomagnetic and geoelectric field variation, Earth-surface impedance, and operational interference (anomalies) experienced on electric-power systems across the contiguous United States during the March 13-14, 1989 magnetic storm. For this, a 1-minute-resolution sequence of geomagnetic field maps is constructed from magnetometer time series acquired at gAuthorsJeffrey J. Love, Greg M. Lucas, E.
