We studied the magnetic properties of active region NOAA 12127 previous to a M1.5-class flare, that was accompanied by a coronal mass ejection, on the August 1, 2014. We estimated the pre-eruptive coronal magnetic field using a non-linear force-free extrapolation, and compared the results with images in Hα and 171 Å. The extrapolated field is able to reproduce the general morphology of the magnetic configurations linked to a filament and several coronal loops identified.
