On 8 April 2024, a total solar eclipse will traverse the continental United States. The totality time will be almost twice that of North American solar eclipse of 2017. This rare event provides a unique opportunity to study the response of the ionosphere and to generate radio images of the Sun during the eclipse. We are constructing a Deployable Low-Band Ionosphere and Transient Experiment (DLITE) station within the path of totality. DLITE is a four-element interferometric radio telescope utilizing Long Wavelength Array antennas. The antennas are separated by 300m, allowing us to distinguish bright cosmic radio sources uniquely situated in the line of the eclipse’s path of totality. Our station will observe from the grounds of Observatory Park in Montville, OH. We will: (i) study the impact of the reduced solar UV radiation on total electron content gradients, (ii) probe turbulent irregularities in the ionosphere, and (iii) produce radio images of the Sun. Beyond the eclipse, the DLITE station will continue monitoring the ionosphere and will search for astrophysical transient sources. The construction and operation of DLITE is student-driven, and we will collaborate to maximize outreach before, during, and after the eclipse.

The DEB Initiative is collaborative citizen science project that establishes a North American solar observation telescope network with the primary goal of creating coronal data set along the 2024 TSE eclipse path from Mexico to Canada. DEB currently has 82 observation teams training to observe the 2024 TSE that include 40 teams funded by NASA SMD and 20 girl group specific teams funded by NSF through a partnership with Einstein's Incredible Universe, a large screen format documentary. DEB teams currently stream solar observation data to debra.physics.siu.edu and will continue to throughout the project. The public may use the site at any time to see observation, however it is mostly intended for public sharing of data during large events such as the October 14, 2023 ASE and the April 8, 2024 TSE as well as our own internal team's use at any time. The DEB telescope network is capturing solar data in the hopes of getting high cadence imagery of solar flares, and capturing coronal data during the 2024 TSE to measure the acceleration of the solar corona to approximately 3X solar radii. Preliminary results from our April 8, 2024 observations will be discussed.
