Here is a FAQ that explains the differences between the C2 camera (red images) and the C3 camera (blue images): http://www.geocities.com/vikrant_narang/soho_comet_hunt_faq.html.
In viewing these chronological images of PX, it appears confusing when first Planet X seems close, then far away. We found this information on zetatalk and provide it to help clarify what is going on.
ZT: [July 7, 2007] We have stated that Planet X pierces the Ecliptic at approximately the halfway point between the Earth and the Sun, 45 million miles or so. At this point, it stands upright and draws the Earth close to it, for a distance of 14 million miles. At this point, the slowing of Earth's rotation to a stop occurs. This would all seem to imply that a single approach of Planet X to the Earth occurs, as then, after the pole shift, Planet X zooms on out of the solar system. The Eastfield crop circle implies that Planet X draws near, then retreats, then draws near again during a severe wobble where it seems to be in two places at once in the sky, then draws the Earth close during the rotation stoppage, then takes off again. At present, Planet X lies close to the Sun in the line of view, so close as to be lost in the glare. Planet X is closing the gap, coming ever closer and will come near enough to be visible to many on Earth. But as we have explained, the Point of Passage places Planet X further from the Earth, as shown by the angles of the ZetaTalk Triangle which appeared in two Wisconsin crop circles on July 4, 2003. As Planet X swings its N Pole toward Earth, there is a clash, the N Pole of Planet X wanting to evade the N Pole of Earth, and vice versa. Thus, Earth pushes back in her orbit as far as possible, creating this distance, so that Planet X will diminish in size. Nevertheless, Planet X is still coming closer, closing the gap, more distance from the Sun, less distance from Earth, even though offset to the right. How will the establishment explain a temporary appearance of Planet X in the sky, followed by a diminished size offset to the right of the Sun, then a reappearance of Planet X in the sky along with a severe wobble? A dancing asteroid? A permanent solar flare that dances around the Sun? And what of the wobble? (http://www.zetatalk.com/index/zeta378.htm)
6/2/09 (3:00 position) may or may not be PX. The image is too small, but it was deleted from surrounding frames, so makes it suspicious it is PX.
7/2/09 (almost noon position) may not be PX.
