Key deliverables include high-resolution Fabry-Perot and Lyot/Halle filter observations of the solar corona, high-frequency (>1 Hz) power spectra measurements of coronal loops to study coronal heating...
This $135,000 National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) supports collaborative research to study the impact of solar eclipses on the ionosphere, a critical region of Earth's atmosphere that affects radio communications and navigation. The lead awardee, the Regents of the University of Colorado (a U.S. state government entity and institution of higher learning), will coordinate multi-instrument observations of ionospheric parameters during...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $394,601 to Southwest Research Institute (SwRI) to conduct research on measuring the solar corona's magnetic field through spectropolarimetric analysis of the neutral helium 1083 nm emission line. The goal is to develop machine learning methods based on the Hanle effect to routinely measure the full vector magnetic field of the solar corona, which will enable improved predictions of coronal...
This Project Grant from the National Science Foundation Division of Atmospheric and Geospace Sciences, totaling $357,172, supports research into small-scale ejections in the sun's photosphere through chromosphere and corona from September 1, 2021 through August 31, 2024. The award is being administered by the New Jersey Institute of Technology under the Geosciences program (CFDA 47.050) to strengthen understanding of the integrated Earth system through basic atmospheric and ocean sciences...
The National Science Foundation (NSF) awarded a $215,044 Project Grant under its Mathematical and Physical Sciences (CFDA 47.049) program to the Southwest Research Institute (SwRI) to conduct the Citizen CATE (Continental-America Telescopic Eclipse) Next-Generation 2024 Total Solar Eclipse Experiment. This collaborative project between SwRI, the National Solar Observatory, and the National Center for Atmospheric Research aims to deploy 40 teams of citizen scientists along the path of the April...
This three-year Project Grant from the National Science Foundation's Division of Atmospheric and Geospace Sciences Geosciences program (CFDA 47.050) provides $150,000 to the New Jersey Institute of Technology to advance understanding of coronal heating mechanisms in the Sun. Through a combination of multi-wavelength microwave imaging observations from the Extended Owens Valley Solar Array and 3D numerical simulations, the grantee will examine the coupling of thermal and magnetic structures...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $166,193 to The Johns Hopkins University to conduct collaborative research on the ionospheric density response to solar eclipses across the United States. The primary objectives are to: 1) quantify how solar eclipses impact the ionosphere's electron density and variations in the F-region height, and 2) identify the key factors driving these ionospheric responses, including reduced solar...
The National Science Foundation awarded a $280,817 Project Grant to the University of Colorado Boulder under the Geosciences federal grant program (CFDA 47.050) from May 15, 2023 to April 30, 2026. The grant supports research to advance understanding of coronal heating and solar wind acceleration processes through multi-messenger data analysis and four-dimensional forward modeling simulations. Specifically, the University will construct line-of-sight models of extreme ultraviolet and X-ray...
This $215,044 Project Grant awarded by the National Science Foundation's Division of Astronomical Sciences supports the Citizen Continental-America Telescopic Eclipse (Citizen CATE) experiment for the 2024 total solar eclipse. The grant will fund the deployment of 40 teams of citizen scientists along the path of totality to collect over 60 minutes of high-resolution polarimetric data on the solar corona. The research aims to better understand the physical processes that shape the heating,...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) aims to improve the understanding of the Sun's corona, the hot outermost layer of the solar atmosphere, by analyzing data from five total solar eclipses spanning 2015 to 2024. The $385,959 grant awarded to the Wentworth Institute of Technology, Inc. in Boston, MA will support the analysis of visible and near-infrared imaging observations made during these eclipses to study the coronal electron temperature, electron density, and magnetic field structure. The findings will be compared to magnetohydrodynamic simulations to benchmark and improve coronal and solar wind models, with the goal of enhancing space weather forecasting capabilities. The project will also provide hands-on research experience for undergraduate students. No subawards are planned under this grant.
