The Research Station for Astrophysics of the Royal Swedish Academy of Sciences runs a 0.5-m solar telescope on La Palma, Canary Islands. The research in solar physics takes advantage of the superb observing site to study small-scale solar phenomena such as granulation, sunspot structure, and small magnetic elements. This is done with techniques for imaging, spectroscopy, and polarimetry that are being developed in Stockholm and on La Palma to allow sub-arcsecond resolution.
