1 MK Sun
Nobeyama Radioheliograph (NoRH) can observe plasmas with temperature of
1 MK (10^6 Kelvin). This figure shows the 1993-3-16 flare.
The left panel shows the soft X-ray image taken by Yohkoh satellite,
and the right panel shows the 17 GHz image taken by NoRH.
The loop-like structre is almost common. But detailed study indicates
the intensity distributions are a little different in these images.
This is because temperature is not uniform in the loop.
