Ground measurements of the geomagnetic field, during the total solar eclipse of July 11, 1991, were carried out at three sites in Costa Rica located within the eclipse's path of totality. Near totality, there was a significant change in the total intensity,F. Its normal decrease in the afternoon hours was interrupted during a period of about 45 min, in whichF varied very little. This was due mainly to a small variation in horizontal intensity,H, during such a period. The departure ofF from normal lasted about 100 min; its maximum departure was near 10 nT and occurred about 38 min after totality, The declination,D, also experienced a small change (about 2.3 min) during the total period of the eclipse. The vertical intensity,Z, and the inclination,I, did not show significant changes.read more

A review of conventional explanations of anomalous observations during solar eclipses
TL;DR: In this article, a review of conventional explanations for observations of anomalous behaviour of mechanical systems during solar eclipses are critically reviewed, focusing on observations of tilt of the vertical, which seems to play an important role in this matter.

The Response of the 11 August 1999 Total Solar Eclipse in the Geomagnetic Field
TL;DR: The last total solar eclipse on August 11, 1999, was observed on an area covered by many geomagnetic observatories and this point offers a unique opportunity to look for respective responses in the geOMagnetic field.

The effect of a solar eclipse on the Earth's magnetic field
TL;DR: In this paper, the effect of an eclipse on electron-currents flowing in the E-layer is examined, and the corresponding magnetic effects are inferred, and it is concluded that the magnetic effects of a solar diurnal magnetic variation are likely to be too small for detection with certainty.
