Helicity: Twist and WritheCertain dynamo models can generate magnetic helicity of one sign on large-scales, writhe, and the opposite sign on small scales, twist.
Most Twist Indicators lost in EmergenceSignificant details of a magnetic field's twist are lost when it emerges through the solar surface, with only weak twist being distinguishable.
Moat Flows subject to Sunspot's PenumbraMoat flows are only present at locations around sunspots where the penumbral field is perpendicular to the umbra's border.
Reversals in Magnetic Signatures during FlaresEroneous reversals can be generated in photospheric magnetic data during flares as a result of non-thermal electron acceleration.
Reconnection can generate Wave SignaturesA series of reversals in the input and output fields during reconnection is termed 'oscillatory' and produces periodic heating and swaying jets.
Interchange Reconnection at WorkReconnection between active regions and coronal holes interchanges positions of closed and open field, hence 'interchange' reconnection.
