Tom Ashcraft in North Central New Mexico shared this graphic of an X1.3 class Solar Flare event that he recorded at his Heliotown observatory there.


SDR-based Radio Telescope Kits are here!

RSP1A photo The Radio JOVE Project is now offering decametric radio telescope kits that use the SDRPlay RSP1A receiver. These enable our participants to observe a range of frequencies simultaneously. See the Kit Orders page.

Video: Historic Maryland — Jupiter Radio Emissions

marker thumbnail A film crew has created a short video on the story behind the Maryland Historic Marker which recognizes the location where the discovery of Jupiter's Radio Emissions took place in 1955.

Historical Note

20+ Years of Radio JOVE:

The Radio JOVE Project turned 20 years-old in 2019! Here's remembering all those who have made the project go over the years, some who are, sadly, no longer with us. Thank you to all those who support and participate in Radio JOVE.

Welcome to Radio JOVE!

team constructing RJ 1.1 kit Radio JOVE students and amateur scientists from around the world observe and analyze natural radio emissions of Jupiter, the Sun, and our galaxy using their own easy to construct radio telescopes.

Our Project announces Radio JOVE 2.0, where participants assemble a 16-24 MHz radio spectrograph to observe solar, Jupiter, Galactic, and Earth-based natural radio emissions and share their observations with fellow participants.
See our JOVE Bulletin to learn what's happening at Radio JOVE.

 Observer's Corner

30 April 2022 – very strong solar radio burst activity was recorded today. Many of these bursts are thought to be associated with an X1 class solar flare. See the excellent data from Hawks Nest Radio Observatory (HNRAO) from Jim Brown in Industry, PA showing Type III (13:43 UT) and Type V (13:50 – 13:58 UT) solar bursts. The top graphs in each pair are calibrated data from the original Radio JOVE receiver at 20.1 MHz and a dual dipole antenna. The spectrographs show the Right-handed Circular Polarization (RCP) from an SDRplay RSP1A connected to a wide band terminated folded dipole (TFD) square antenna array. Because the solar emission is mostly unpolarized, the new Radio JOVE kits (SDRplay RSP1A and a dual dipole) would show similar spectrograph data.
