Description
This paper reports on our new findings from the International Time
Program observations at the Canaries islands, Spain, in July 2005. We
have found small-scale photospheric events with extremely red-shifted
Stokes V signals in sunspot moat regions. A preliminary estimate of the
physical conditions for an observed Stokes V profile indicates the
presence of a downward motion with a supersonic speed in the order of 10
km/s. With the currently evaluated observational information, we
interprete the supersonic flows as downward motion from magnetic
reconnection occurring at the upper chromosphere or lower photosphere.
With coordinated observations of the Solar-B onboard telescopes, Stokes
measurements by the SOT spectro-polarimeter would give new information
for further understanding the nature of these events with strongly
red-shifted Stokes V, and for discussing the physical conditions
involving in possible magnetic reconnections in the lower solar
atmosphere.
