Abstract : Observations of solar magnetic fields and associated activity, obtained with a Magnesium b-line (5172 A) Etalon Filter, are described. Particular emphasis is placed on flares visible in the wings of the Magnesium line; such flare structures are of small size (4-6 arcsec) and their intensities are strongly correlated with soft x-ray fluxes.
