It is a 6-m dish, tracking the Sun automatically from ~7h30 until ~16h00 UT everyday. It is used for the spectral observations. The dish hosts two antenna, one for the low frequency part of the spectrum (Callisto and ARCAS), mounted as piggy-bag on the side of the dish, and one for the high frequency part of the spectrum (HSRS), installed at the focus of the parabolic dish.


It is a 3.4-m dish, installed on one of the refurbished telescope of the old solar interferometer. It is tracking the Sun from nearly Sun rise to Sun set. It used for the SAFIRE flux monitoring project.
