The Dynamic Eclipse Broadcast (DEB) Initiative is a collaborative scientific effort to create a North American network of volunteer citizen scientist solar observation teams that is led by Southern Illinois University Carbondale. Teams receive training and become part of the network that will conduct coordinated solar observations leading up to and during the 2023 annular and 2024 total solar eclipse.  All DEB sites (currently 81) upload images to our image server debra.physics.siu.edu while the observation site is active including during practices.  Selected observation sites will stream live video produced in partnership with SolarSTEAM and NASA EDGE during the April 8, 2024 total solar eclipse. Live stream links to video will be available on eclipse.siu.edu.  Compelling images from the partial phases of the eclipses, and science quality data from the path of totality will be collected from volunteer observers from Mexico, across the US, and in Canada. Inexpensive camera and telescope systems, combined with new data analysis techniques, will enable scientifically valuable observations of these upcoming solar eclipses. DEB will provide context observations for all of the 2024 eclipse experiments by showing the evolution of the white light coronal structures and the solar disk during the 90 minutes of totality throughout North America.

Observations will produce scientific results through:

1. Coronal observations during the 2024 total solar eclipse.
2. Solar and lunar limb observations during the 2023 annular solar elcipse.
3. A variety of day and night time follow on projects.

The DEB Initiative will produce dynamic coronal images of the 2024 eclipse by equipping 80+ teams along the path of totality. The HDR images that teams capture will be combined into a movie showing coronal evolution and allowing scientific analysis of the Sun’s inner corona in a similar way to our 2017 effort, the Citizen CATE Experiment.

DEB builds on the success of our 2017 Citizen CATE Experiment and includes several improvements. DEB engages groups throughout North America with observations from any location thus removing limitations of geographical location or the ability to travel to the narrow path of totality of a total solar eclipse. Night time follow-on observations are enabled through the use of a GoTo mount to accurately point and track celestial targets. DEB Initiative follow-on projects will feature exoplanet transit observations like those already achieved with CATE volunteers, to which we add variable star and asteroid light curve observations, and climate change relevant atmospheric optical depth measurements from across North America.

DEB is funded by NASA Science Mission Directorate and he National Science foundation.  Observation teams will receive equipment and training at no cost. DEB utilizes relatively cheap amateur astronomy equipment and standardized software to reduce costs for imaging setups to ~ $1,800. Teams that already have their own adequate laptop or amateur astronomers possessing their own compatible equipment such as a tracking mount can participate at much lower costs.
