INAF-OAR also contributes to the digitization and analysis of the time series of historical full-disc solar observations taken over the last century, e.g.

The PSPT produces daily seeing-limited full-disk digital images various spectral bands, with a 0.1% pixel-to-pixel relative photometric precision. INAF-OAR has operated the PSPT (Precision Solar Photometric Telescope) since July 1996 in the framework of projects aimed to understand the processes responsible for solar irradiance variations. Synoptic observations of the Sun From left to right, CaII K (393.4nm), blue continuum (409.4 nm), G-band (430.6 nm) and red continnum (607.1 nm) full-disk images obtained on with the PSPT (Precision Solar Photometric Telescope) at the INAF OAR. IBIS-A is realized in a joint effort of Italian research groups contributing to the SOLARNET project. INAF-OAR leads the IBIS-A will be soon integrated in the SOLARNET-SVO and US-VSO Virtual Solar Observatory archives. Currently, IBIS-A includes 7.7 TB of data taken during 8 observing campaigns carried out from 2012 to 2016 on 39 days. The IBIS-A has been designed to realize the storage, the management, and the retrieval of the IBIS data through a VO compliant archive.

The IBIS data Archive (IBIS-A) contains data acquired with IBIS (Interferometric BIdimensional Spectropolarimeter), an imaging spectro-polarimeter based on a dual Fabry-Perot interferometric system. Another company involved in the design of the instrument is BDP Engineering & Manufacturing S.c.a.r.L. The project is a fruitful example of cooperation between research institutions (INAF) and industry (Dal Sasso/AVALON). The first channel of the instrument will see its first light at the beginning of 2017, only one year after the arrival of the first funding. In 2014 Dal Sasso srl with its brand AVALON Instruments, in partnership with INAF-OAR as scientific advisor, proposed a robotic tomographic telescope for the monitoring of the solar activity, based upon magneto-optical filter technology. Since then, INAF-OAR has also contributed to the FP7 SOLARNET (2013-2017), which brings together and integrates the major European research infrastructures in the field of high-resolution solar physics, to the H2020 GREST (2016-2019), which is intended to take the European Solar Telescope (EST) to the next level of development by undertaking crucial activities to improve the performance of current state-of-the-art instrumentation, and to the H2020 PRE-EST (2017-2020) that will address the legal, financial, and socio-economic issues for the attainment of the EST in the next decade.

INAF-OAR contributed to the study of various parts of the telescope and lead the activities aimed at the definition of requirements and preliminary design of the observatory control and data handling.

The project has involved 29 partners, plus 9 collaborating institutions, from 15 different countries. EST Conceptual Design was financed by the European Commission within the FP7. It will be optimised for studies of the magnetic coupling between the deep photosphere and upper chromosphere.

Left: high spatial resolution broad band image of a bipolar magnetic region in the solar photosphere acquired with the spectro-polarimeter CRISP at the Swedish Solar Telescope (La Palma, Canary Islands). The research, which is carried out observational activities and analysis of data, also extends to investigation of heliophysics, by considering the impact of solar variability on Earth’s climate, space weather, and space climate. The research focuses on the atmosphere of the Sun with its rich structure, dynamics, and variety of phenomena, as revealed by observations carried out with state-of-the-art ground-based and space-born telescopes.
