DOI: 10.1007/s11207-018-1380-8
Abstract: Defining the solar brightness temperature accurately at millimeter wavelengths has always been challenging. One of the main reasons has been the lack of a proper calibration source. New Moon was used earlier as a calibration… read more here.

DOI: 10.1093/mnras/stad1232
Abstract: Small flares frequently occur in the quiet Sun. Previous studies have noted that they share many common characteristics with typical solar flares in active regions. However, their similarities and differences are not fully understood, especially… read more here.
