Identity of temperature characteristics of the coronal hole above the solar north pole on March 29, 2006 and coronal holes on a background of the quiet Sun
This paper is devoted to the analysis of temperature characteristics of polar, middle-latitude and low-latitude solar coronal holes at centimeter wavelengths during the periods of solar activity minimum. Observational data of the polar coronal hole have been obtained with the RATAN-600 radio telescope during the solar eclipse of March 29, 2006 (Golubchina et al., 2011; Golubchina, Korzhavin, 2013, 2014). Observational data of the middle-latitude and low-latitude coronal holes, and also quiet Sun have been obtained with RATAN-600 and LPR (Large Pulkovo Radio Telescope) and resulted in works (Borovik et al., 1990; Borovik, 1994). The coincidence of some temperature characteristics of the centimeter radio emission from the middle-latitude and low-latitude coronal holes, and polar coronal hole above the solar north pole testifies to the identity of temperature characteristics of greater coronal holes irrespective of the way of their creation and location on the Sun during the periods of solar activity minimum.
