Solar Orbiter and ground-based observations: lessons from SOHO/TRACE
Abstract
Due to the flexibility and/or superiority of ground-based observations in spectral coverage, cadence, spatial resolution, targeting, and especially bandwidth issues, they are often very complementary to space-based observations. Coordinating ground-based efforts with spacecraft data comes with specific operational issues, of which seeing conditions, cross-instrument coordination, and co-alignment or targeting are the most critical for success. Successful coordination has shown promise for a much improved understanding of the connectivity between the photosphere and the corona, because is allows the study of the highly dynamic and finely structured intermediate layers through which the energy transport from the photosphere to the corona takes place. I will demonstrate these issues by taking a close look at recent results obtained with the combination of SOHO, TRACE and the SVST (Swedish Vacuum Tower Telescope in La Palma). I also briefly discuss how new or future ground-based technologies and instruments will be able to complement Solar Orbiter.
