A flux comparison of northern and southern Saturn kilometric radio bursts during southern summer

Abstract : The energy flux of the northern (N-) and southern (S-) Saturn kilometric radiation (SKR) bursts are statistically compared. We investigated the N- and S-SKR bursts from 2005 DOY 250 to 2006 DOY 200, when Cassini was close to the equatorial plane and RPWS could simultaneously observe both N- and S-SKR. We identified 38 burst events, and compared their flux from southern (summer-side) and northern (winter-side) hemispheres. In the main band (100-400 kHz), S-SKR bursts from the summer-side hemisphere were 5-6 times stronger than the N-SKR bursts from the winter-side. This is not far from the flux ratio in the non-burst status. In the low-frequency extension (10-50 kHz) of SKR bursts, this ratio is smaller, about 2-3 times.
