It has faded bigtime now on the 16:06 shot from SOHO.

It's in the top-right, about halfway between the vertical and the big black line from the arm holding that disc in front of the Sun. Apparently the motion and quick dimming is pretty in line with it being debris from a destroyed comet as opposed to a small nucleus surviving perihelion. Considering that latest image is more than 2 hours old, I wonder if the comet's remains will even be visible by the next published photo.
