Radio Jove Spectrograph Users Group (SUG)

Professional and amateur radio astronomers working together to record and analyze Jovian dynamic spectra leading to a better understanding of Jupiter's decametric radio emission process. Or, herding cats for radio astronomy. Your choice.


Here are two documents describing who and where we are, what we do, and why we do it:
The SUG (2015) and SUG Capabilities (2016) and SUG Station Distances (2016)

More info about the Radio Jove program may be found here:
Radio Jove Project Home Page and Radio Jove Data Web Site


The following sections contain links to information of use to researchers and observers of Jovian decametric radiation.
