Motivations

Funders (NSF/CISM)





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

Details

Based on AAVSO & HAIL original concepts
Redesigned by teachers & EE PhD students

2 versions:






SID – inexpensive (~$250), for high schools
AWESOME – research quality (~$3000), for
community colleges and universities
Preassembled, but students build their own
antenna
Data useful to students & researchers;
centralized data repository & blog
Access to Scientist Mentors

Funding

NSF – Center for Integrated Space
Weather Modeling (CISM)


Development (both SID & AWESOME)
NASA – MDI/SOHO, HMI/SDO, &
separate grant


Funding test placement of 100 monitors
Funding distribution throughout world for
IHY 2007
4
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 up to 192 countries
around the world.
Stanford alumni volunteers are translating our
documents into the 6 official languages of the UN
(Arabic, Chinese, English, French, Russian, Spanish)
Funding from NASA grant (amount still unknown)
5
Science Goals


Understand the causes & effects solar activity has
on the Earth, (eventually 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)

Both SID & AWESOME data are being used by
researchers & students
6
Educational Goals



Inspire & excite students in science by
giving them hands-on access to “real”
data
Target underserved populations
Spread the knowledge of our solar
system and the exciting process of
scientific exploration to students of the
world.

The Sun, ionosphere,
and radio waves

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

Our Monitors

AWESOME


SID






Low Cost (~$250)
Single band
1 sample/5 seconds
Preassembled & tuned
Students build antenna
Available free to
underserved schools





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
