The Solar Cycle
Across
- 1. the most violent type of energetic phenomena in the sun
- 4. these reverse every 11 years from the northern to the southern hemisphere.
- 6. this is generated and amplified from the combined effects of rotation and convection
- 7. a period of time when only a few sun spots are seen
- 9. Approximately four years into a cycle when the number of sun spots are at their highest
- 11. when magnetic field lines go above the surface dragging plasma and forming arcs
Down
- 2. a constant jet stream of charged particles from the solar corona. They are somewhat to blame for the tails of comets pointing away from the sun.
- 3. a 22-year old cycle that is often shown by images of an 11-year cycle.
- 5. a lengthy period of solar inactivity from 1645-1715
- 8. when magnetic fields form bubbles instead of arcs
- 10. one of the oldest known types of solar activity where magnetic field lines trap the solar plasma and convection stops
- 12. this cycle is set to peak in mid-2013 and will be much less active than normal
