  1. Overview of Sun-Earth Connections • Fundamental Ideas from SEC • Why Should Teachers Care? • The sunspots are coming, the sunspots are coming….Solar Maximum is Here!

  2. Fundamental Concepts from SEC • The Sun is dynamic • We live in the atmosphere of the Sun • Earth responds to the changing sun -- that response is known as space weather • Scientists study the Sun-Earth Connection using data from spacecraft, ground stations, supercomputers, and rocket experiments

  3. The Sun is dynamic, not constant • Our Sun is a big, hot, massive star • It has cycles -- sunspots, fast and slow solar wind, magnetic field reversals, irradiance -- time scales from seconds to a million years • Quiet features -- solar wind, rotation, emitting different radiations/wavelengths • It has the astrophysical equivalent of storms and weather -- CMEs, flares, prominences, filaments, radio bursts

  4. We live in the atmosphere of the Sun • Space is not a vacuum - filled by dynamic, blustery solar wind extending far beyond the planets • Interaction between the solar wind and the Earth's magnetic field produces a cavity around Earth -- the magnetosphere • Solar wind/system carves a place in the galaxy/interplanetary space

  5. Earth responds to the changing sun • That response is known as space weather • Space (particularly around Earth) is a tough place to live and work • Effects of SEC activity are visible at Earth -- aurora and airglow are examples • Space weather effects our systems and society, principally technology
