Description of Ionograms:
Computation of ionospheric electron density from the black line plasma resonance frequency in ionograms

Approximately:

NumberElectronsPerCubicCentimeter =

1.24E4 * PlasmaResonanceFrequencyInMHz^2

Example, at 10 MHz , 1.2E6 electrons per cubic centimeter

At 4 MHz , about 1.9E5 electrons per cc



 Typical electron densities

Eclipse 170821 preparations - Solar Eclipse Balloon launch from Carbondale Illinois, with Student participation

http://eclipse.siu.edu/lsu-researchers-students-plan-solar-eclipse-balloon-launch-siu/

"...At 90,000 feet, the video camera will be able to see some 200 miles out toward the horizon. Guzik said it may be possible to see the moon’s shadow coming toward Carbondale at a distance, though the group will have little or no control over which way the camera is pointed at any given time..."

NASA Eclipse Resources

From NASA's Education Message for May 11 :

"....On Aug. 21, 2017, the United States will experience a solar eclipse! This celestial event will provide a golden opportunity to engage and educate diverse audiences, and NASA has the resources to help.

Along a path 60 to 70 miles wide stretching from Oregon to South Carolina, observers will be able to see a total solar eclipse. Others across North America will see a partial eclipse. The event will happen around lunch time across the country. For an interactive map with timing information along the path of the eclipse, visit

http://eclipse.gsfc.nasa.gov/SEgoogle/SEgoogle2001/SE2017Aug21Tgoogle.html.

Visit the following websites to find additional information and resources, including:
-- Tips for safely viewing the solar eclipse.
-- Recorded interviews with NASA scientists, mission specialists and eclipse path communities.
-- Topical online eclipse videos, featuring a variety of STEM and cultural topics.
-- Social media community development and networking.
-- Mobile educational eclipse applications.
-- Public challenges and engagement activities.
-- 2-D and 3-D printing exercises for K-16 students.
-- Citizen science campaigns in partnership with NASA mission observations.
-- Adjunct activities and educational resources.
-- Live streaming of observations and programming.

Amateur Radio and Science HamSCI


The HamSCI 2017 Eclipse Experiment Description

http://hamsci.org/about-hamsci

Very good page:

http://hamsci.org/projects/2017-total-solar-eclipse/2017-eclipse-experiment-description


"...What is HamSCI?

HamSCI, the Ham Radio Science Citizen Investigation, is a platform for the publicity and promotion of projects that are consistent with the following objectives:

Advance scientific research and understanding through amateur radio activities.
Encourage the development of new technologies to support this research.
Provide educational opportunities for the amateur community and the general public.

HamSCI serves as a means for fostering collaborations between professional researchers and amateur radio operators. It assists in developing and maintaining standards and agreements between all people and organizations involved.  HamSCI is not an operations or funding program, nor is it a supervisory organization. HamSCI does not perform research on its own. Rather, it supports other research programs, such as those funded by organizatons like the United States National Science Foundation..."
