  1. 554. Energy Distribution Heating Events Observed During the May 2020 Solar Orbiter Perihelion
    Olena Podladchikova (PHYSICAL-METEOROLOGICAL OBSERVATORY DAVOS / WORLD RADIATION CENTER (PMOD / WRC))

    Session 2 - The Solar Atmosphere: Heating, Dynamics and Coupling
    Poster

    High resolution observations of the solar corona with the EUI telescope onboard the Solar Orbiter mission during the perihelion campaign at 0.56 AU revealed omnipresent impulsive quiet-un emissions in the 174 A filter, at previously unresolved temporal/spatial scales. Individual brightenings of the smallest linear size till 0.2Mm show temporal variability within tens of seconds. These...

  2. 148. Features of the physical characteristics of the radiation of polar coronal holes in the Sun according to observations in the radio range

    Session 2 - The Solar Atmosphere: Heating, Dynamics and Coupling
    Poster

    The article presents a brief overview of the main results of observations of the radio emission of polar coronal holes (CD) on the Sun, obtained in a wide range of wavelengths (m-mm) on various radio telescopes. The results of observations of the polar coronal hole (CD) on RATAN-600 in a wide centimeter wavelength range (1.03-30.7) are analyzed. The obtained physical characteristics of the CD...

  3. 371. Nanojets of Coronal Heating

    Session 2 - The Solar Atmosphere: Heating, Dynamics and Coupling
    Poster

    The solar corona is shaped and mysteriously heated to millions of degrees by the Sun’s magnetic field. It has long been hypothesized that the heating results from a myriad of tiny magnetic energy outbursts called nanoflares, driven by the fundamental process of magnetic reconnection. Misaligned magnetic field lines can break and reconnect, producing nanoflares in avalanche-like processes....

  4. 553. Statistical spectroscopic analysis of a quiescent prominence observed in hydrogen Lyman lines by SoHO/SUMER and MgII h&k lines by IRIS
    Dr Pavol Schwartz (Astronomical Institute, Slovak Academy of Sciences)
    09/09/2021, 11:39
    Session 2 - The Solar Atmosphere: Heating, Dynamics and Coupling
    Poster

    A quiescent prominence was observed on October 22, 2013 at NW limb quasi-simultaneously and nearly co-spatially in the Lyman line series of hydrogen by SoHO/SUMER and in MgII h&k UV lines by IRIS. In this contribution we analyze a dense and compact structure of the prominence because this part is quiet and therefore suitable for quasi-static non-LTE modeling. This part of the prominence is...

  5. 139. Probing chromospheric heating in active regions with millimeter interferometry
    Dr João M. da Silva Santos (Stockholm University)
    09/09/2021, 11:52
    Session 2 - The Solar Atmosphere: Heating, Dynamics and Coupling
    Poster

    The interaction between emerging magnetic fields and the preexisting magnetic canopy in active regions is a complex process but essential for understanding the onset of transient brightenings driven by magnetic reconnection and their role in energy/mass deposition in the chromosphere and above.

    We present the results of a comprehensive analysis of SST, ALMA, and SDO observations of a solar...
