Solar Atmosphere: Big Bear Solar Observatory, 1972

Film Specifications - 16mm film ; Description - Film depicts shots of sunrise, water, the Big Bear Observatory, its massive telescope, shots of the solar atmosphere. The photosphere, time-lapse shot of granules through spectrograph. Solar spectrum. Lines indicate gases, Doppler Effect. Granules rise and fall. Simulation of sun surface, and photosphere. Solar pores and sunspots. Large enough to swallow a dozen earths. Many groups of spots, or none at all. In 1970, and 1980 many spots. Special filters. Hot Hydrogen gas . Clouds absorb and allow other spectrum energy through. Graphs and animations. Chromosphere, several thousand kilometers above the Photosphere. Bright red color. Dark and light spots. Edge of Sun. Spicules. Strong magnetic fields. Dominate structures of Chromosphere.  Magnetic field lines. Size and shape of sunspots, over time. Activity of sunspot groups. Can measure magnetism. Strongest in sunspots.  Sunspots over 60 days.  Long dark clouds over sun. Large prominences. Time-lapse. Jets of gas. Solar limb surges. Pnumbra waves. HUGE flares. Immense energy released. Affects polarities. flares affecting filaments. 1000K per second. Cannot predict activity. Filament movements. Titanic forces. Atmosphere blocks damage to earth. Solar eclipse. Rarifies gas. Shows the corona. Filter to green light. Time-lapsed Loops into corona. Computer animation of magnetic fields from sunspot groups. Solar wind. Solar atmosphere. Much more to be learned. Great narration and soundtrack.  ; Location - Sun as viewed through many observatories. ; B & W ; Sound ; Date - Feb. 1972 ; Reel Size - 12" ; Approx. Film Length - 850' ; Approx.
