The Solar Eclipse of April 17: The Annular Eclipse as Observed near Chavenay, France

The solar eclipse observed by Clavius in A . D . 1567

The careful description of the solar eclipse of A.D. 1567 by Clavius is used to derive limits to the Earth’s rotational clock error (∆T) of between 145 and 165 sec at this date. This result provides an important link between the ∆T curve as deduced from ancient and medieval eclipse observations and that obtained from telescopic data.

The solar eclipse: a natural meteorological experiment

A solar eclipse provides a well-characterized reduction in solar radiation, of calculable amount and duration. This captivating natural astronomical phenomenon is ideally suited to science outreach activities, but the predictability of the change in solar radiation also provides unusual conditions for assessing the atmospheric response to a known stimulus. Modern automatic observing networks us...
