Use of a spectral line to show granules percolating in the photosphere is followed by a discussion of sunspots. Spectroheliography is used to illustrate a variety of solar phenomena. The movie finishes with computer graphics of the solar magnetic field and some idea concerning solar wind. Solar energy experiments are featured. This Meeks computer-generated film beings by showing the motions of the Pleiades and Hyades over 300,000 years.
Proper motion is defined followed by moving cluster parallax.
The distribution of open clusters is plotted before globular clusters are shown. Following a discussion of their characteristics, their distribution is also plotted. A brief history of the observations if given. Each of the two components is shown to be a spectroscopic binary. Sponsored by a watch company.
