Summary of Connecticut 76‐Hz vertical electric, transverse magnetic, and radial magnetic field‐strength comparisons

The results of 60 days of vertical electric‐field and 136 days of radial horizontal magnetic‐field measurements taken in Connecticut are summarized in this article. The main results are (1) the vertical electric field‐strength behavior usually is very similar to the transverse horizontal magnetic field‐strength behavior (in both amplitude and relative phase) during both normal and disturbed‐propagation conditions, (2) during normal‐propagation conditions, the radial magnetic field‐strength amplitude behavior usually is similar to the transverse magnetic field‐strength amplitude behavior, while the radial magnetic field‐strength relative‐phase variation usually is somewhat greater than that for the transverse magnetic field strength, and (3) during disturbed‐propagation conditions, the daily radial and transverse magnetic field‐strength plots, versus GMT, usually are dissimilar (in both amplitude and relative phase). In particular, the radial magnetic field‐strength variations usually are greater than the transverse magnetic field‐strength variations.
