title: Geophysical variables and behavior: LXXX. Periodicities and energetic characteristics of a strobe-light luminosity during a geomagnetic storm.
abstract: A videotape of a "strobe-light" luminosity that occurred in northern Ontario for several minutes during the evening of 6 October, 1994, at the time of a geomagnetic storm, was analyzed frame by frame. Brightness of the flashes decreased over the time of the observation. The interflicker intervals displayed phase-shifted periodicities that would be compatible with a rotating electromagnetic dipole and with the observations of the witnesses. The time of the occurrence and the dynamics of the luminosity were consistent with the predictions of the tectonic strain hypothesis.
