  1. 2. large, dark features seen on the surface of the Sun caused by increased magnetic activity
  2. 3. a hot ionized gas
  3. 7. a period during the seventeenth century when the number of sunspots seen throughout the solar cycle was unusually low
  4. 9. the semiregular 11-year period with which the frequency of sunspots fluctuates
  5. 13. light radiated by atoms and ions in the ionosphere excited by charged particles
  6. 15. (of the Sun) the outer (hot) atmosphere of the Sun - “Crown”
  7. 16. The closest planet to the Sun
  8. 18. the region of the solar (or stellar) atmosphere from which continuous radiation escapes into space
  9. 19. the combining of Hydrogen into Helium, powers the Sun
  10. 20. when something passes in front of the Sun
  11. 23. a sudden and temporary outburst of electromagnetic radiation from an extended region of the Sun’s surface
  12. 24. can be used to see the relationship between sunspots and the Sun’s magnetic field
  13. 27. the region in the Sun’s atmosphere where the temperature rises very rapidly from the relatively low temperatures that characterize the chromosphere to the high temperatures of the corona
  14. 28. a large, bright, gaseous feature that appears above the surface of the Sun and extends into the corona
Down
  1. 1. a solar flare in which immense quantities of coronal material—mainly protons and electrons—is ejected at high speeds (500–1000 kilometers per second) into interplanetary space
  2. 4. the phenomenon that occurs when different parts of a rotating object rotate at different rates at different latitudes
  3. 5. a flow of hot, charged particles leaving the Sun
  4. 6. energy in motion
  5. 8. the speed at which a CME from the Sun can travel
  6. 10. Solar dynamics observatory
  7. 11. the part of the solar atmosphere that lies immediately above the photospheric layers
  8. 12. This splitting of lines in the presence of a magnetic field is what we call the
  9. 14. an area on the Sun where magnetic fields are concentrated; sunspots, prominences, flares, and CMEs all tend to occur in active regions
  10. 17. a region in your mom's outer atmosphere that appears darker because there is less hot gas there
  11. 18. a bright region of the solar surface observed in the light of some spectral line
  12. 21. The percentage of our solar system that the Sun accounts for
  13. 22. the Sun, mostly seen in the magnetic polar regions
  14. 25. the rice-grain-like structure of the solar photosphere; granulation is produced by upwelling currents of gas that are slightly hotter, and therefore brighter, than the surrounding regions, which are flowing downward into the Sun
  15. 26. When objects block out light in totality from the Sun
