Bottom Row: SWAN enters the field of view of the STEREO COR1 beacon images. Left image, approaching the Sun. Right image, The faint trace of the comet appears to wrap around the Sun. Image sources, NASA SOHO and STEREO respectively.
Comet SWAN continues it's plunge to the Sun, and appears to be evaporating, in the low resolution STEREO beacon images a faint trace of the comet can be seen rounding the Sun, it's unlikley anything will come out the other side. We will have to wait for the high resolution images to see what is really happening.
