| Abstract: |
We present the results of spectropolarimetry observations of
active region NOAA 9664 in photospheric Fe I 6302 Å and
chromospheric Mg I b2 5872 Å spectral lines simultaneously. The
active region was situated near the disk center at the time of our
observations. Among several interesting features, we observe six
compact, down-flow regions, each about two arc seconds in size near
the magnetic neutral line. The Stokes V profiles at these locations
are normal in the chromosphere but anomalous in the photosphere. The
corresponding Stokes I profiles are symmetric in the chromosphere and
highly asymmetric in the photosphere. We discuss possible origin of
these features as a result of bending of penumbral Evershed flow
channels as neutral line light bridges are formed in δ-spots. |
