| Summary: | Previous studies have shown that the occurrence probability of Saturn
Kilometric Radiation (SKR) appears to be influenced by the local time of
Titan. Using a more extensive set of data than the original study, we
confirm the correlation of higher occurrence probability of SKR when Titan
is located near local midnight. In addition, the direction finding
capability of the Cassini Radio Plasma Wave instrument (RPWS) is used to
determine if this radio emission emanates from particular source regions. We
find that most source regions of SKR are located in the mid-morning
sector of local time even when Titan is located near midnight. However, some
emission does appear to have a source in the Saturnian nightside, consistent
with electron precipitation from field lines that have recently mapped to
near Titan. |
