VELOCITY AND 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 magnetic field.

 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 calibration.

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.
