We observed Jupiter's synchrotron radiation at frequencies of 15 and 22 GHz using the VLA (Very Large Array) in its most compact configuration (D-array) in March 1991. The spatial brightness distribution of the emission at these high frequencies appears to be very similar to that seen at lower frequencies (5 GHz down to 330 MHz). We measured a total nonthermal flux density at 15 and 22 GHz of 1.5 +/- 0.15 Jy and 1.5 +/- 0.4 Jy, respectively (both normalized to a geocentric distance of 4.04 AU). These numbers agree well with model spectra of Jupiter's synchrotron radiation that were obtained by fitting the planet's nonthermal radio emission between 74 MHz and 8 GHz and suggest a maximum cutoff in electron energies at ~100 MeV. The degree of linear polarization observed with the VLA is 21.5 +/- 1.9% at 15 GHz.
