Observing solar phenomenas with the large solar vacuum telescope

Abstract

The large solar vacuum telescope (LSVT) was designed to study solar phenomenas with high spatial and spectral resolution. Due to the large size of the telescope, its real spatial resolution may be as high as ≈0.4 arcsec, which makes it possible to observe fine-structure solar phenomenas like Ellerman bombs and pores. At present, the main subjects of investigation are solar flares. The LSVT research methods—spectral, spectropolarimetric, and filter—provide valuable information on the physical parameters in the phenomenas under study. Spectra and images of the Sun are recorded through an birefringent filter by two CCD cameras.
