The ionosphere is then opaque to Jovian signals from shortly after sunrise to a few hours after sunset. Sometimes we refer to a “Jupiter observing season.” At solar maximum the season is only several months long when Jupiter and the sun are far apart in the sky. At solar minimum the season can be almost the whole year long as reception is possible even when the sun and Jupiter are close together in the sky. During solar minimum the ionosphere can remain transparent for Jovian signals during daylight hours. Although the ionosphere will be transparent and allow Jovian signals through when Jupiter and the sun are close together in the sky, those signals will generally be weaker when Jupiter is at its maximum distance from earth at conjunction compared to when Jupiter is at opposition. + Learn More [ 22 July 2019 ] Modifying the RJ1.1 Antenna for Jupiter at Low Declinations Reminder : Jupiter is currently at about -22 degrees declination. Observers in the northern hemisphere should consider adapting the standard dual dipole antenna configuration to lower the main lobe of the antenna beam to the south. See Richard Flagg's earlier newsletter article about adjusting the dual dipole. News & Features Archive » -- the birth of planetary radio astronomy Jupiter's natural radio emissions were first discovered near Seneca, Maryland. In 2005, Radio JOVE and the Carnegie Institution Department of Terrestrial Magnetism recognized the 50th anniversary of this discovery and helped publicize this milestone with a variety of events and presentations.
