Coronal transients during two solar minima: Their source regions and interplanetary counterparts

Mostrar todas las versiones(3)

We have investigated two full solar rotations belonging to two distinct solar minima, in the frame of two coordinated observational and research campaigns. The nearly uninterrupted gathering of solar coronal data since the beginning of the SOHO era offers the exceptional possibility of comparing two...

description We have investigated two full solar rotations belonging to two distinct solar minima, in the frame of two coordinated observational and research campaigns.
