MAGNETIC OBSERVATIONS OF THE SUN
The Velocity And Magnetic
Observations of the Sun (VAMOS) is a project by the solar group at
the INAF - Osservatorio Astronomico di Capodimonte (INAF-OAC), to
conduct a full-disk study of solar photospheric dynamics and
VAMOS is a solar imager, based on the technology
of the magneto-optical filter (MOF), to obtain high cadence
observations of the intensity (I), velocity (V) and longitudinal
magnetic field (B) at the photospheric level.
The instrument, with two potassium vapour cells, became
operational in May 1999, and is used for campaign observations.
Since 2001, the VAMOS is located in the East tower of the INAF-OAC.
Data reduction software has been developed for both the Doppler
images calibration and the V and I images spherical harmonic
decomposition. Progress is underway to perform the B images
Currently, the science done by VAMOS deals with the study of
photospheric dynamics, based on the analysis l-nu diagrams for V
and I power, I-V phase difference and coherence.
