Description
A case of cancellation of magnetic fields is observed during the decay
of a small active region. Three different sources of information were
simultaneously used: high resolution magnetograms, chromospheric Ca II
filtergrams and transverse velocity fields. A magnetic structure is
apparently dragged to the network by the supergranular velocity field
while it splits into two. There, they meet another structure with
opposite magnetic polarity. After a period of coexistence, the magnetic
pairs vanish, leaving no trace of either magnetic or chromospheric
structures.
