1. LIVE INTERACTIVE LEARNING @ YOUR DESKTOP NASA/NSTA Web Seminar: Living and Working in Space: Energy http://institute.nsta.org/web_seminars.asp

2. Living and Working in Space: The Solar Cycle and Space Weather Terry Kucera Scientist with the STEREO and SOHO Missions NASA/GSFC • The Sun and Solar Activity • Magnetic Fields • Space Weather

3. I heard Terry Kucera (the presenter) at the Face-to-Face Symposium in Baltimore: YES NO

4. What is the most common element on the Sun?

5. Alex Lutkus

6. Sun Scale Facts: - You can fit 109 Earths across the disk of the Sun - Driving at a speed of 55 mph it would take almost 200 years to drive from Earth to the Sun Alex Lutkus

7. Let’s do a poll question! What state of matter is the Sun?

8. The Sun: Visible Light Sept. 22, 2000 SOHO/MDI

9. The Sun: Ultraviolet Light, Sept. 22, 2000 SOHO/EIT 286 A

10. The Sun Sept. 22, 2000 SOHO/MDI SOHO/EIT 286 A

11. The Sun Radiates More than Just Light Coronal Mass Ejections (CMEs) SOHO/LASCO, ESA & NASA The Sun’s Corona in Visible Light

12. Question: How long does it take for radiation from a CME to travel from the Sun to the Earth?

13. High Energy Protons from the Sun (a.k.a Solar Energetic Particles or SEPs) SOHO/LASCO July 14, 2000 NASA & ESA

14. UC Berkeley

15. Solar Magnetic Loops TRACE NASA

16. Solar Cycle NASA

17. Solar Max or Solar Min? SOHO/MDI, ESA & NASA SOHO/MDI, ESA & NASA

18. Solar Max or Solar Min? SOHO/EIT ESA & NASA

19. Solar Max or Solar Min? Windows to the Universe http://www.windows.ucar.edu

20. Earth’s Magnetosphere Without the solar wind the Earth’s magnetic field would be like a bar magnet. The solar wind compresses it on the Sun-ward side and stretches it on the far side. Windows to the Universe http://www.windows.ucar.edu

21. Question: Does anyone know any of the ways that solar activity can affect Earth or human activities? Press *6 to unmute your phone and respond

22. Solar Activity - Space Weather Solar Flare Intense Extreme UV, X-rays Arrival: 8 min Solar Energetic Particles (SEPs) Arrival: 15 min - hours Protons at almost the speed of light Coronal Mass Ejection (CME) Arrival: 1 - 4 days Magnetic field and plasma Flare Big Bear Solar Observatory SEPs SOHO/EIT, ESA & NASA CME SOHO/LASCO, ESA & NASA

23. Space Weather: CMEs and Geomagnetic Storms Windows to the Universe http://www.windows.ucar.edu

24. Space Weather: CMEs and Geomagnetic Storms Some Results: Aurora, Power System Problems Public Service Electric & Gas Corp. Image courtesy of Jan Curtis.

25. Have you seen an Aurora? Where were you?

26. Aurora from Space POLAR NASA

27. Space Weather: Drag on Satellites in Low Earth Orbit Flares heat outer atmosphere causing increased drag on satellites Hubble Space Telescope drops 10-15 km per year After a big flare 100’s of spacecraft have to be relocated NASA STS-103

28. Space Weather: Radiation Hazards to Spacecraft and Astronauts NASA

29. Space Weather: Communications Problems Windows to the Universe http://www.windows.ucar.edu

30. Spacecraft NASA

31. STEREO - just launched NASA
