Description:
Scientific Objectives: A long, continuous study of the quiet Sun is requested to form a heritage data-set that will be suitable for a variety of scientific investigations both for current and future solar researchers. Request to SOT HOP Number 0059 Magnetograms are important for identifying magnetic cancellation/emergence events, while G-band and Ca II are important for identifying release at photospheric/chromospheric heights that can be related to the transition region/coronal emission observed with EIS. NFI Mg I magnetograms should be interspersed with BFI Ca II and G-band images. The BFI focus should be optimised for Ca II. Time cadence does not need to be high, and both NFI and BFI should have a FOV in X of at least 180h (to match EIS), and have the full field of view in Y. It is important that a regular and consistent mixing of the three filters should be maintained during the 72 hour observation period to obtain a homogeneous data-set.
