Amateur astronomy has evolved dramatically over recent years. A motivated amateur, with his/her backyard instrument and adequate processing software is nowadays capable of; recording high-resolution planetary images in different wavelengths (better in fact than many professional observatories could achieve say 15 years ago), following stellar occultations by giant planets' atmospheres, or high-precision photometry of exoplanet transits. Other committed amateurs use dedicated cameras or radio-antennae to provide continuous meteor-detection coverage of the sky near their location.

Hundreds of regular observers are sharing their work, providing a very good coverage of the main visible planets (Jupiter, Saturn, Mars and Venus) which is very valuable at a time when professional astronomers face increasing competition accessing resources, which often have to be shared with other areas of research. Additionally, these networks of amateur observers can react at very short notice when triggered by a new event occurring on a solar system object requiring observations.

Moreover, some advanced amateur astronomers use advanced methods for analysing their data meeting the requirements of the modern researcher, thereby facilitating regular and close collaboration with professionals. Often this leads to publication of results in peer-reviewed scientific journals. Examples include; planetary meteorology of Jupiter and Saturn, meteoroid or bolide impacts on Jupiter, asteroid and cometary research, and studies of Venus.

This session will showcase results from amateur astronomers, working either by themselves or in collaboration with members of the professional community. In addition, members from both communities will be invited to share their experiences of pro-am partnerships and offer suggestions on how these should evolve in the future.
