Abstract : From August 1976 to December 1978, extremely low frequency (ELF) field-strength measurements were taken continuously in Connecticut. The results of measurements taken from March through May 1978 are discussed in this report. During March, 5 dB, or greater, nighttime signal fades occurred during 46 percent of the measurement days. A comparison of the normal and abnormal Connecticut horizontal magnetic-field strengths during distributed propagation conditions revealed atypical behavior. Field-strength measurements were also taken before, during, and after the 29 April PCA event (9.8 dB riometer absorption).
