Description:
Request to SOT HOP Number 0192 BFI Ca II H /G-b, time cadence 60 sec NFI 5250 A/Mg I b 5172A IVDG, time cadence 30 sec SP high resolution fast maps 20?hx82?h Other Instruments: TRIPPEL @ SST Scientific Objectives: The goal of this proposal is to coordinate Hinode with SST where mainly spectroscopic observations will be carried out. We would to focus on two targets:(1) quiet Sun/plage region @ disc center: Recent studies based on realistic 3D simulations show that significant percentage of type I spicules might be produced by magnetic energy releases in the photosphere. Temperature increase at these locations, as well as high velocity flows, should be direct signatures of these events. By combining the spectroscopy in lines that probe different heights with the polarimetric signal obtained with Hinode/SOT, we will try to locate these events and follow their evolution.(2) active region: We intend to study convective motions and structure of umbral dots, penumbral fibrils and light bridges. We will try to obtain temperature and velocity profiles in low-mid photosphere.
