Students and science enthusiasts are invited to catch a real-time look at radio astronomy as scientists explore magnetic hotspots on the Sun during a live, virtual solar eclipse event on April 8, 2024.<\/p>\n

A massive, 34-meter telescope once used by NASA\u2019s Deep Space Network to communicate with spacecraft will point towards the Sun during the solar eclipse that day. The Moon\u2019s position in front of the Sun will help the antenna detect radio waves from solar active regions in more detail than is usually possible.\u00a0<\/p>\n

The Solar Patrol team at California\u2019s Lewis Center for Educational Research, in partnership with NASA\u2019s Jet Propulsion Laboratory, will remotely operate the Goldstone Apple Valley Radio Telescope (GAVRT) while sharing observations and commentary during an interactive webinar open for the public.\u00a0<\/p>\n

Scientists and students regularly use the single-dish GAVRT antenna, located in the Mojave Desert of California, to scan the Sun. They use the observations to build maps of radio waves formed along strong magnetic field lines in the outer atmosphere of the Sun. By studying these images, researchers can measure the strength and structure of those powerful magnetic regions. These observations offer insight into magnetically driven processes on the Sun, like solar flares and coronal mass ejections, which generate space weather events that can interfere with satellite electronics, radio communications and GPS signals, spacecraft orbits, and power grids on Earth.\u00a0<\/p>\n

During the April 8, 2024, total solar eclipse, NASA\u2019s Jet Propulsion Laboratory, educators at the Lewis Center for Education Research in Southern California, and participants in the center\u2019s Solar Patrol citizen science program will use the Goldstone Apple Valley Radio Telescope (GAVRT) to observe solar \u201cactive regions\u201d \u2013 the magnetically complex regions that form over sunspots \u2013 as the Moon moves over them.

During normal solar observing, GAVRT can only detect and distinguish relatively large features on the Sun. A solar eclipse offers a unique opportunity for GAVRT to capture sharper and more refined information about the magnetic field structure in the solar active regions that are often marked by sunspots.<\/p>\n

\u201cIt\u2019s special during the eclipse because, as the Moon is passing in front of an active region, that really sharp edge of the Moon covers up more and more of the structure in that active region,\u201d says Marin Anderson, a research scientist at NASA\u2019s Jet Propulsion Laboratory and GAVRT Solar Patrol scientist.\u00a0<\/p>\n

Anderson explains how, as the Moon blocks a portion of the active region, it\u2019s easier to tell what part of the active region the radio emissions are coming from.\u00a0<\/p>\n

\u201cIt\u2019s basically a way of probing magnetic field structures in the corona of the Sun in a way that we wouldn\u2019t be able to unless an eclipse was happening.\u201d\u00a0<\/p>\n

Anyone in the world can join the live-streamed webinar on April 8 from 1-3:30 p.m. EDT (10 a.m. to 12:30 p.m. PDT) and ask the hosts questions as a partial eclipse becomes visible in California. Participants will be able to see the telescope controls, data visualization tools like Helioviewer<\/a>, incoming radio data, a map of active hot spot regions, and imagery of the eclipsed Sun at radio wavelengths.\u00a0<\/p>\n
