SOLIS - A modern facility for synoptic solar observations
Authors:
C. U. Keller and NSO staff
Abstract:
SOLIS (Synoptic Optical Long-term Investigations of the Sun) is a
suite of instruments that will modernize and greatly improve synoptic
solar observations carried out by the National Solar Observatory. It
will provide fundamental data necessary to understand the solar
activity cycle, sudden energy releases in the solar atmosphere, and
solar spectral irradiance changes. State-of-the-art instrumentation
and data collection techniques will be employed to enhance both the
quality and quantity of data. A high degree of automation and remote
control will provide faster user access to data and flexible
interaction with the data-collection process. The instruments include
a vector spectromagnetograph that will measure the magnetic field
strength and direction over the full solar disk in 15 minutes, a full
disk patrol delivering digital images in various spectral lines at a
high cadence, and a Sun-as-a-star precision spectrometer to measure
changes in many spectral lines.
