A transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and Earth. The Venus transit as seen in the 171 wavelength. This channel is especially good at showing coronal loops - the arcs extending off of the Sun where plasma moves along magnetic field lines. The brightest spots seen here are locations where the magnetic field near the surface is exceptionally strong.
