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: YESNO

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

5. Alex Lutkus

6. - 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 Sun Scale Facts: Alex Lutkus

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

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/EIT 286 ASOHO/MDI

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

12. 8-10 minutes 1-2 hours1-4 days2-3 weeks1-5 months Question: How long does it take for radiation from a CME to travel from the Sun to the Earth?

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

14. UC Berkeley

15. Solar Magnetic Loops TRACE NASA

16. Solar Cycle NASA

17. Solar Max or Solar Min? 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 SEPs SOHO/EIT, ESA & NASA CME SOHO/LASCO, ESA & NASA Flare Big Bear Solar Observatory

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 Image courtesy of Jan Curtis. Public Service Electric & Gas Corp.

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 NASA STS-103 Hubble Space Telescope drops 10-15 km per year After a big flare 100’s of spacecraft have to be relocated

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
