| Abstract: |
Moving Magnetic Features (MMFs) are small-size magnetic elements that
are seen to stream-out from sunspots. Although several observations
suggest that MMFs are closely related to the existence and presence of
penumbral filaments, there are some very few observations that report
MMFs streaming from pores and sunspots after the penumbra has
disappeared. Here we report on the first high spectral, spatial and
temporal resolution observations of type II and III MMFs streaming out
from a small pore and compare our results with previous observations
of features streaming out from penumbrae. We analyzed
spectro-polarimetric observations of NOAA 11005 acquired with the IBIS
instrument at the Dunn Solar Telescope in the Fe I 617.3 nm and the
Ca II 854.2 nm spectral lines, and in the G-band. We show that the
characteristics of the investigated MMFs agree with those reported in
the literature for MMFs which stream out from spots with penumbrae. We
believe that our results provide new information that might be helpful
in the future development and upgrade of numerical modeling of the
generation of MMFs in the lack of a penumbra. |
