Since 1980, only spacecraft or space telescope have been able to image spokes (intermittently appearing radial or elongated dark markings in Saturn’s B-ring) around the planet equinoxes. Amateur astronomers’ observations from Earth have been increasing in quality and coverage since a few years, leading around the 2009 equinox to the first ground observations, with a good coverage of Saturn’s rings. Combining these with amateur observations of white spots associated to storms (cf. [1]) can give… 
Amateurs’ contributions to Saturn study during and after the Cassini era
During the Cassini mission around Saturn, amateurs’ observations were useful to follow the evolution of the features observed by Cassini with the Imaging Science Subsystem cameras. It also proved

Saturn's Spokes: Lost and Found
TLDR
It is shown that the charging environment above the rings has prevented the formation of spokes until very recently and is capable of stopping spoke formation entirely and restricting the size of the particles in the spokes.

TLDR
Within Saturn's rings, the "birth" of a spoke has been observed, and surprising azimuthal and time variability is found in the ringlet structure of the outer B ring, leading to speculations about Saturn's internal structure and about the collisional and thermal history of the rings and satellites.
