Description
We have analyzed high temporal frequency VL observations acquired by
Metis during the perihelia on March, October 2022 and April 2023.
In particular, we focused on series of total and polarized Brightness
observations lasting for 40 min up to few hours, acquired with a
cadence of 20 s and 60 s.
The field of view of the observations ranges from 1.7 to 3.5 solar radii.
We have found in these data sets several examples of inflows, which we
identify as collapsing loops and outflows, identified as density
inhomogeneities (blobs), likely due to magnetic reconnection.
These phenomena have been associated with the coronal magnetic
structures and dynamics derived from a MHD model, and are
compared with the theoretical simulations.
