- Photosphere
- region in the solar atmosphere from which most of the visible light escapes into space
- Magnetic Dynamo (Babcock's theory)
- explains phenomena of the solar cycle as a result of periodic winding and unwinding of the sun's magnetic field
- Sunspot Minimum
- the time during the solar cycle when the number of sunspots is minimum
- Limb darkening
- the phenomenon whereby the sun is darker near its limb than near the center of its disk
- Sunspot Maximum
- the time during the solar cycle when the number of sunspots is greatest
- Filaments
- dark curve seen above the sun's photosphere that is the top view of a solar prominence
- Plage
- bright spot on the sun believed to be associated with an emerging magnetic field
- Differential Rotation
- rotation of a nonrigid object in wich parts at different latitudes or different radial distances move at different speeds
- Prominences
- frame like protrusion seen near the limb of the sun and extending into the solar corona
- Heliosphere
- bubble in space containing the sun and planets created by the solar wind
- Corona
- sun's most outer atmosphere
- Solar Cycle
- 22 year cycle during which the sun's magnetic field reverses its polarity twice
- Supergranule
- large convective cell in the sun's chromosphere containing man granule
- Sunspots
- temporary cool region in the solar photosphere created by protruding magnetic fields
- Solar Flare
- violent eruption on the sun's surface
- Granule
- lightly colored convection features about 1000 kilometers in diameter seen constantly in the solar photosphere
- Maunder minimum
- with a period of cold in europe so extreme that it was called the little ice age
- Coronal Holes
- dark region of the sun's inner corona as seen at X-ray wavelengths
- Plasma
- hot ionized gas
- Chromosphere
- ayer in the solar atmosphere between the photosphere and the corona
- Tranisition Zone
- region between the sun's chromosphere and corona where the temperature skyrockets to about 1 million K
- Coronal Mass Ejections
- large volumes of high energy gas release from the SUn' corona
- Spicule
- narrow jet of rising gas in the solar chromosphere
- Solar Wind
- outward flow of particles from the sun
