Observing Tips - Jupiter's Decametric Radio Emissions

Typical Jovian radio storms are not very strong as heard with the Astro-1 or RJ 1.1 telescope.
-- You must maximize your chances by picking the best opportunities, selecting a good observing site, and using good observing techniques.
During the daytime, the Earth's Ionosphere blocks Jupiter's radio emissions.
-- Observe Jupiter at night.
Radio noise from electrical sources, such as power lines, fluorescent lights, computers, and motors, can mask the signals from Jupiter.
-- Select an observing sight away from buildings and power lines.
Jovian radio storms may be short in duration.
-- Persistence and luck are needed to capture Jupiter's radio signals.
Nighttime observing from a temporary field setup can be dangerous.
-- PLAN CAREFULLY!! Get permission in advance to use the site, set up before dark, and use caution when walking around the site at night.
Nearly all common portable tape recorders use an automatic recording level control circuit (ALC). The ALC can mask the variations in the Jovian L bursts.
-- Use a tape recorder that allows you to SWITCH OFF the ALC). Keep the ALC turned off.
