Emergence of magnetic flux and organisation on the surface of the Sun

On the solar surface there is a continual emergence of magnetic flux, distributed over various spatial scales; this can lead to the formation of active regions, of ephemeral regions, be added to the intranet work magnetic field or be distributed over even smaller scales, not resolved with present instruments. In order to contribute to the understanding of these problems, a series of coordinated observational campaigns are necessary, making use of both ground-based (IBIS at the DSR/NSO or the Goettingen Fabry-Perot at the VTT in Tenerife or the CRISP at the SST in La Palma) and satellite-based (SOHO-MDI, HINODE, SDO) instruments, so as to gain information on the various layers of the solar atmosphere and the magnetic configuration of the regions observed.
Also, the understanding of the predicted phenomena could be achieved by studying the emergence of magnetic flux tubes from the convection zone to the solar surface, via the development of 3D, numerical, MHD simulations, using appropriate codes with Adaptive Mesh Refinement.

MISTRAL, a wind of change in the SRT observations

May 29, 2025

MISTRAL, a wind of change in the SRT observations MISTRAL is a new-generation receiver for observations at millimeter wavelengths, built as part of the recent project to upgrade the Sardinia Radio Telescope for the study of the high-frequency radio universe. The main features of this instrument are the very high number of detectors cooled to temperatures close to absolute zero and a dedicated cold optical system, which allow for extremely sharp images. MISTRAL made its “first light” by observing three different celestial objects: the Orion Nebula, the radio lobes of the supermassive black hole in the galaxy M87, and the supernova remnant Cassiopeia A. These images represent the first scientific observations at 90 GHz ever obtained using the SRT
