Both amateur and professional broadcasters have been sending and receiving radio signals around the Earth for over a century. Such communication is possible due to interactions between our Sun and the ionosphere, the ionized region of the Earth’s atmosphere located roughly 40 to 400 miles overhead. The upcoming total solar eclipse on April 8, 2024, provides a unique opportunity to study these interactions. As HamSCI members transmit, receive, and record signals across the radio spectrum during the eclipse, you will create valuable data to test computer models of the ionosphere.

During a total solar eclipse, however, observers can see the corona – and scientists can investigate how solar material moves out from the Sun to form the solar wind, an ever-flowing particle stream that impacts Earth and our entire solar system.The Dynamic Eclipse Broadcast (DEB) Initiative, led by Bob Baer and Matt Penn of Southern Illinois University in Carbondale, organizes volunteers as they capture images of the corona during the 2024 eclipse. Using identical instruments at more than 70 different locations across North America, participants document the moment-by-moment appearance of the corona throughout the eclipse. Comparing these images across locations, scientists track plumes of solar material in the difficult-to-study inner corona, estimating their speed and rate of acceleration and linking these observations to those from NASA spacecraft.The project expands on the team’s efforts during the 2017 total solar eclipse, this time including observation sites outside the path of totality, where part of the solar disk will remain visible. Images from these locations will reveal the source of solar material later observed as outflows in the corona, allowing the team to trace them back to their origins on the Sun.DEB Initiative is one of many participatory science projects happening during the 2024 total solar eclipse.

Students collaborate with scientists who are working on the same mission and are recognized as part of the science team. Data collected and analyzed by the students is used by NASA in their studies of the solar system.During the April 8, 2024, total solar eclipse, NASA’s Jet Propulsion Laboratory, educators at the Lewis Center for Education Research in Southern California, and participants in the center’s Solar Patrol citizen science program will observe solar “active regions” – the magnetically complex regions that form over sunspots – as the Moon moves over them. The Moon’s gradual passage across the Sun blocks different portions of the active region at different times, allowing scientists to distinguish light signals coming from one portion versus another. The technique, first used during the May 2012 annular eclipse, revealed details on the Sun the telescope couldn’t otherwise detect. || ", "release_date": "2024-02-21T08:00:00-05:00", "update_date": "2024-03-12T10:40:40.706097-04:00", "main_image": { "id": 1089303, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a014500/a014530/GAVRT_Thumbnail.png", "filename": "GAVRT_Thumbnail.png", "media_type": "Image", "alt_text": "Music Credit: “Fly Beyond Instrumental” Magnum Opus [ASCAP] via Universal Production MusicComplete transcript available.", "width": 1280, "height": 720, "pixels": 921600 } } ], "sources": [], "products": [], "newer_versions": [], "older_versions": [], "alternate_versions": [] }
