AVAILABLE RADIO DATA AT JUPITER: DECAMETRIC (inputs from H. Rucker, 2008) Ukrainian T-shaped Radio AVAILABLE RADIO DATA AT JUPITER: DECAMETRIC (inputs from H. Rucker, 2008) Ukrainian T-shaped Radio telescope UTR-2, Kharkov, Ukraine http: //www. ri. kharkov. ua/index. html The Ukrainian T-shaped Radio telescope, second modification (UTR-2) is the world's largest radio telescope at decameter wavelengths. The UTR-2 comprises 2040 array elements in two arms: north-south (1800× 60 m) and west-east (900× 60 m). It has a collective area of 150, 000 square meters, and a resolution of about 40'× 40' at the middle frequency 16. 7 MHz. The operating frequency range is 10 -28 MHz. The sensitivity is about 10 Jansky. The telescope is a part of the Ukrainian decametric VLBI system URAN, which includes another four radio telescopes of smaller size. The system has bases from 40 to 900 km. Corresponding data archive: Space Research Institute, Graz, Austria Involved personnel: Alexander KONOVALENKO [email protected] kharkov. ua Observatoire de Nancay, Réseau Décamétrique Nançay http: //www. obs-nancay. fr/ The decametric array of Nancay (Reseau Decametrique Nancay, RDN) is dedicated to the study of the electromagnetic radio emission of Jupiter, the sun and the stars. The instrument operates between 10 -80 MHz, and consists of 144 helical antennas, distributed over an area of 10, 000 square meter. The 8 conducting wires on each antenna have been wound in a spiral pattern on a conical surface. They are wound in either a left- or a right-handed winding spiral pattern, making them sensitive to either left- or right-hand circularly polarized radio waves.

AVAILABLE RADIO DATA AT JUPITER: DECAMETRIC (list not exhaustive) University of Florida Radio Observatory AVAILABLE RADIO DATA AT JUPITER: DECAMETRIC (list not exhaustive) University of Florida Radio Observatory http: //ufro 1. astro. ufl. edu/ Log-spiral Array: The main antennas used at UFRO for monitoring the Jovian Decametric Emission are two arrays of conical log spiral elements. Each array has eight elements; one array is right-hand the other left-hand circularly polarized. Each conical log spiral element (TP) is about 8 meters tall and has a diameter of about 5 meters at the base. The TP is a broad band element and has been designed to work over a wide range of frequencies. For monitoring the Jovian Decametric Emission the UFRO TP arrays are used in the frequency range from 18 to 40 MHz. The arrays have a fixed beam array in the E-W direction but it can be phase-steered in the N-S direction. The E-W half-power beam width is about 90 degrees and allows the observation of Jupiter for a total of about 6 hours (+/- 3 hours around transit).

REYES LOFAR (Low Frequency ARray) http: //www. lofar. org/ LOFAR is a (future) radio telescope network, using an array of simple omni-directional antennas centered at Exloo, NL, with planned outpost radio stations in Germany (part of them already deployed), France, UK, Poland, Italy, and other EU countries. LOFAR consists of a large number of distributed low-cost wire antennas and will make observations in the frequency ranges 30– 80 MHz, and 120– 240 MHz, with the intended French LOFAR superstation (LSS) the frequency is extended down to 10 MHz.
