PublicationChromospheric polarity reversals on sunspots. Are they consistent with weak line emission?
Photospheric and chromospheric solar magnetograms sometimes show opposite polarity. This intriguing phenomenon is associated with the emergence of magnetic flux...

PublicationChromospheric reversals in the emergence of an ephemeral region
Context: The behaviour of both ephemeral regions and moving magnetic features has been often described for the photospheric layer, but not for the chromosphere...
