Preparation of a second station for the measurement of solar oscillations of low degree 'l'

An observing station to detect low-degree global solar oscillations is already operational at the Jet Propulsion Laboratory. A second station for continuative measurements of such oscillations has recently been installed and successfully tested in Rome. The high transmission and stability of the magneto-optical filter (MOF) coupled with the lock-in amplifier technique allow analog and real-time detection of oscillation modes with a noise level of only a few cm/s. Observing runs and estimates of the signal-to-noise ratio are shown in time and frequency domains. Routine observations will establish whether the MOF sensitivity and stability are suitable for the detection of stellar oscillations.
