1. A Unique Collaboration Between Scientists and Educators Deborah Scherrer, Ray Mitchell, William Clark, Richard Styner, Philip Scherrer, Umran Inan, Morris Cohen, Justin Tan, Shannon Lee, Sharad Khanal, Scott Winegarden, Hao Thai, Paul Mortfield Stanford University and Local Schools Designing Sudden Ionospheric Disturbance Monitors

2. 2 Quick Overview Motivations The Plan Objectives The Monitors – SID and AWESOME Structure Speed Bumps The Team

3. 3 Motivations Funders Research experience for teachers & students Long-term relationships between teacher interns & scientists More under-represented students into science Quantitative results Educators Experience with how scientists think & do Content knowledge Hands-on, real science, to take back to the classroom Build EXCITEMENT & enthusiasm for science amongst students Scientists Educators support their research Effective experience for teachers Tap expertize of teacher Minimize overhead of training & supervision

4. 4 The Plan Team community college & high school educators with scientists to: Design, develop, & classroom-test VLF radio receivers that track changes to the Earth’s ionosphere caused by solar activity Provide hands-on, authentic science experience for teachers and students Gather data useful to researchers

5. 5 Details Based on AAVSO original concept 2 versions: SID – inexpensive (~$150) AWESOME – research quality (~$3000) Preassembled, but students build their own antenna (~$10) Centralized data repository & chat site

6. 6 Objectives Place 100 SIDs and 15 AWESOMES Target under-represented high schools & community colleges Leverage from CISM Partners Teacher workshops University application Integration into teacher-training courses Access to web-based training Distribute in a Partnership model, to encourage scientist-teacher collaborations

7. 7 Scientific Goals Understand the causes & effects solar activity has on the Earth, hopefully for prediction capabilities (daytime data) Understand the electrodynamic coupling between the troposphere, mesosphere, and the lower ionosphere driven by lightning and thunderstorm systems (nighttime data)

8. 8 IHY 2007 The United Nations and organizers of the International Heliophysical Year, 2007, have designated these Space Weather Monitors as official IHY instruments, to be placed in 191 countries around the world.

9. 9 The Sun, ionosphere, and radio waves

10. 10 VLF Transmitters 200 ’ Towers Antenna Wires 24 around the world “ NLK” 24.8 KHz Navy Radio Station, Jim Creek, WA 1 cycle = 7.5 miles (12 km) VLF signals can be received all over the world, because of the ionosphere! Primarily U.S. Navy stations for communicating with submarines

11. 11 Our Monitors SID Low Cost (~$150) Single band 1 sample/5 seconds Preassembled & tuned Students build antenna Available free to underserved schools AWESOME Moderate cost (~$3000) Broadband; sample rate of 100kHz on each channel Capture ELF/VLF frequencies ~30 Hz - 50kHz Dual use system: Daytime: monitor solar activity Nighttime: monitor atmospheric phenomena (e.g. lightning) So sensitive that nearly any signal above the ambient Earth noise floor can be detected Data useable for ionospheric and solar researchers

12. 12 Detecting Solar Flares – SID(s) SID Events! Not all events are readily explainable – students can research these

13. 13 GOES-12 Weather Satellite Detecting X-Rays

14. 14 Connecting SID to GOES Data C4.5 C5.9 C3.8 M1.3 Students have also found flares not cataloged by GOES!!!
