| Abstract: |
The cancellation is a convergence and a disappearance of the two opposite polarities and is thought as
a main process of the flux disappearance in the photosphere.
We investigate the spatial structures and time evolutions of Doppler velocity field around the cancellations in
the quiet Sun by using Filtergram (FG) onboard Hinode.
We found the characteristic redshifts in 7 cancellations, blue shifts in 2 cancellations, and no characteristic Doppler velocity
in 3 events.
It is found that the stable downflow is coincident with the flux decrease.
These results suggest that the Omega-loop submergence is a dominant scenario in the cancellation of the quiet Sun. |
