Mojave Solar ... Looking at the Sun's Makeup

Mojave Solar is a private research venture of the Eddy Company, makers of Optical Coating Equipment. We run one of the few private solar helioseismology facilities in the world - the majority being operated by Universities or Government labs. Our solar telescope collects magnetic and Doppler data for dissemination to various researchers.

Mojave Solar, located in Southern California's Mojave Desert, enjoys well over 180 clear days per year, allowing the collection of high quality helioseismology data. This data is distributed via the Internet, as well as through more traditional channels, such as magnetic tapes.

 What is Helioseismology?

The description of helioseismology is currently under construction. Please check back soon to see it in its finished state.

The science of helioseismology is primarily a study of the internal structure and dynamic processes that operate within our Sun, and other stellar objects we see at night. First developed in the early 1960s, it wasn't until the mid-1970s that helioseismology became a truly innovative science. Advances in the ability to view acoustic pressure movements (through polarized and filtered systems) led to this rather specialized astrophysical branch of acoustical spectroscopy.

Being an enormous spherical collection of gases, the Sun acts as a very effective and efficient multi-modal acoustic resonator. Due to a variety of causes within the Sun, oscillations of many types are constantly under formation. Many of these oscillations tend to destructively counteract with one another. The lines of noise that survive tend to align themselves to a five-minute oscillating pattern - with a rather impressive acoustical spectrum - all arranged within a two-octave span.

Although it has been known for several years that our Sun changes as it traverses its 11-year cyclic activity pattern, those known changes have been physical and on the surface. One aspect of helioseismology delves into the plasma streams and expanding gaseous fluxuations that make up our fusion-powered neighbor. The collection of ground-based research facilities, such as Mojave Solar, and an ever-increasing armada of space-based platforms, are just now allowing us to slowly peel away the outermost layer of what is, in many ways, the most important object in this stellar system.
