Example text

The first is the still unanswered question of what and how much change occurs in the various outputs of the Sun as the sunspot number waxes and wanes. This includes not only its various components of heat and light but also the flow of solar particles in the space between the Sun and Earth. The second need is for a more complete understanding of worldwide circulation, weather, radiation, and climate. Atmospheric physicists are now able to model the complexities of global weather and climate with advanced computers.

It took another century and more before eclipses were used to observe the Sun as a physical object, following the coming of photography and spectroscopy. Interest in the chromosphere, prominences, am 1 corona grew rapidly in the 19th century, and eclipse experiments were devised to answer the 120° 180° 120° 180° 60° 30 120' CALCULATED TRACKS of total solar eclipses, 1970-90. In these 21 years, only 14 total solar eclipses occur and only two cross the United States. On the dates indicated, observers located along the paths shown will see the Sun fully eclipsed, but only for the few minutes when the shadow of the Moon races over Earth.

They can be seen outside the eclipse with spectroscopes and other special instruments. The smallest prominences are about the size of Earth, and some have been seen that are as large as the Sun itself. Their temperatures, densities, and, therefore, their spectra are like that of the chromosphere, and we now consider prominences as cooler, denser chromospheric material that extends into the hotter, rarer, corona. Prominences appear in many forms. Some develop into explosive features that lift off the Sun as great eruptions into space.
