High-resolution observations of the solar granulationDigitally-enhanced high-resolution images from space and ground observatories have yielded data on the solar granulation which show it to be a more complex combination of phenomena than previously suspected. These new data have been used to detect large-scale horizontal flows over the solar surface through direct measurements of granule proper motions. The results thus obtained may have important implications for the heating of the solar chromosphere and corona. The observed intensity pattern on the surface of the sun is noted to be due not only to granulation, but the superposition of different types of waves as well. All such phenomena are modified in the presence of magnetic fields, becoming smaller and of reduced contrast.
