Abstract

Over the last decade the unprecedented uninterrupted, high resolution, coverage of the Sun has led to the discovery of many new types of small-scale phenomena, as well as a better understanding of phenomena such as X-ray bright points. Due to the excellent range of telescopes aboard these many spacecraft the small-scale phenomena have been observed in many different wavelengths. Much has been discovered over the past 10 years about them, but there are still many questions to be answered. What are the connections between all these different small-scale transient phenomena? How are they created? Do they contribute to the heating of the solar corona and if so, how significant is their contribution? Are any of them the source of the fast solar wind? Six key types of phenomena from the quiet and active Sun are reviewed. Their connections to the magnetic field below and to other coronal phenomena are discussed.
