More than 150 space physics researchers, educators, engineers, college students, licensed amateurs, and members of the Ham Radio Science Citizen Investigation (HamSCI) community came together at the sixth annual HamSCI Workshop on March 17 – 18, 2023, where they listened, learned, and contributed to scientific investigations involving the Earth’s ionosphere and magnetosphere. This year’s workshop was presented by The University of Scranton, and it emphasized cooperation between HamSCI’s professional science community and its volunteer citizen scientists, many of whom are active amateur radio operators.
