Editorial: The Sun seen with the Atacama Large mm and sub-mm array (ALMA)—First results1

Abstract

et al. comes next, where the results on the temperature structure of the chromosphere, the chromospheric Figure 1. ALMA images of the Sun at 1.3 mm (band 6). Left: Full disk image obtained by scanning with a single dish; the spatial resolution is 30 . Right: High resolution (1 ) image of the region around the sunspot, obtained in interferometric mode with mosaicking. Both images were obtained on December 18, 2015, during the commissioning period and were processed by the authors for better visibility of the disk features.network and spicules are presented, followed by the research article by Tarr et al., which compares the 23 3 mm brightness temperature with the Hα line width in the weak solar network. (Rutten, 2017), with brilliant ideas and acute but constructive criticism. He will be remembered by the 45 entire solar physics community, and we dedicate this Research Topic to his memory.This work makes use of the following ALMA data: ADS/JAO.ALMA.2011.0.00020.SV. ALMA is a partnership of ESO (representing its member states), NSF (USA) and NINS (Japan), together with NRC 48 (Canada), MOST and ASIAA (Taiwan), and KASI (Republic of Korea), in cooperation with the Republic
