Jovian radio emission during the impact of a Shumeyker-Levi comet
(1994)

The radiation of the Jupiter in a continuous spectrum on frequency 1665 MHg was measured on the radio-telescope RATAN-600 from July 15 till July 31 in azimuth 30 deg. with horizontal linear polarization (the -plane was under a angle 1.5 deg. to equator of the Jove). On measurements of a reference source (3C 218, flux of 32.5 Jy) error measurements of flows has appeared about 2%. Results of measurement of Jovian flux, enumerated on a standard distance 4.04 , are displayed on figure 1a. The attempt is made to divide a response of a magnetosphere of the falling comets into two parts: immediate responce during impacts and more delaed one. On figure 1b the relation of the measured flows to a relative phase is showed and the data from July 17 till July 23 are excluded. Despite of small quantity of data precisiouly, sinusoidal relation from phases is obvious, however amplitude and phase of a sine wave sharply differ from their values in a quiet condition. The values of fluxes with excluded sinusoidal component are displayed on figure 1c. It is visible, that between July 19 and 20 the increase of a flux was begun, reaching on July 22 29% +- 2% from mean value of a flux.
Thus, disturbance of a magnetosphere of the Jupiter, reflected in increase of a flux of decimeter radio emission immediately in period fallings and the next week, has appeared rather essential.
