Summary

Description
English: This is a false-color, 3-layer composite from the TRACE observatory showing the solar corona: the blue, green, and red channels show the 171Å, 195Å, and 284Å, respectively. These TRACE filters are most sensitive to emission from 1, 1.5, and 2 million degree plasma, thus showing the entire corona and detail of coronal loops in the lower solar atmosphere). The image shows the corona for a moderately active Sun, with some (red) hot active regions in both hemispheres, surrounded by the (blue/green) cooler plasma of the quiet-Sun corona. Notice the multitude of relatively cool loops connecting the active regions on both hemispheres.
