Levy. Sky darkening Some of the ideas I offer in these pages come from O’Meara’s excellent article An eclipse timetable. 2 If the eclipse is a slight one, where less than half of the Sun is covered, a casual observer will not notice any significant drop in the ambient light. The light level can actually be measured qualitatively by recording the color and quality of the sky, and of any clouds which might be passing by. Record your results not just on the sky or clouds, but also on nearby objects and distant landforms.

When the program ended I rushed out and stopped the exposure. The resulting image shows the Moon as a long bright streak setting in the west, Venus setting next to it, and the tracks of several airplanes descending to land at Tucson International Airport. Photograph by David H. Levy. Total eclipses are rare and magnificent, but partials are much more frequent. Because they also show the motion of the solar system in real time, they can be inspiring events. If one occurs near you, be sure not to miss the show.
