The comet was seen by both the STEREO Ahead and Behind spacecraft, allowing the position and shape of the comet tail to be measured in three dimensions. http://cor1.gsfc.nasa.gov/images/thumbnails/sungrazer_singleview_thumb.jpg http://cor1.gsfc.nasa.gov/images/movies/050107.mpg Here is an unusual event observed by STEREO on May 1, 2007, off the northeast limb of the Sun. There was the "tornadic" motion of the prominence seen in Helium II (304 Angstrom); then what can only be described as a "blob" moved extremely slowly (<10 km/s) through the low corona, with non-radial motions through the MLSO MK4 and COR1. The "blob" seemed to "evaporate" at the trailing portion of what appeared to be an elongated fluxrope CME without any clear front. More study necessary to explain this one! http://cor1.gsfc.nasa.gov/images/thumbnails/050107_thumb.jpg http://cor1.gsfc.nasa.gov/images/movies/May2007_COR1_AB.mov Wavelet-enhanced images from May 2007, taken every six hours from COR1-A and COR1-B. http://cor1.gsfc.nasa.gov/images/thumbnails/May2007_COR1_AB_thumb.jpg http://cor1.gsfc.nasa.gov/images/movies/June2007_COR1A.mov Assembled and image-processed using a wavelet enhancement technique by Dr. Guillermo Stenborg.

It is named "halo" CME when the leading edge of the particle cloud appears as an expanding arc around the Sun, something we can see, though faintly, in this video. The ejected material is either heading more or less directly towards or away from the viewer. In this case, the event was judged to have occurred on the backside of the Sun as we saw no evidence of an event on the front side. The video clip cover about 8 hours of activity. http://cor1.gsfc.nasa.gov/images/thumbnails/20070730_stillB.jpg http://cor1.gsfc.nasa.gov/images/movies/2007-May-20.mpg An apparent "halo" CME detected in Total Brightness on 20-May-2007 http://cor1.gsfc.nasa.gov/images/thumbnails/2007-May-20_thumb.jpg http://cor1.gsfc.nasa.gov/images/movies/2007-May-22.mpg TotalB movie of a multipart CME(s) on the West limb on 22-May-2007 http://cor1.gsfc.nasa.gov/images/thumbnails/2007-May-22_thumb.jpg http://cor1.gsfc.nasa.gov/images/movies/2007-Jul-08.mpg COR1 detection of a CME off the SE limb on 08-July-2007. It was difficult to detect the leading edge of this event, but there was a strong "concave-out" trailing feature, remniscent of a flux rope morphology. http://cor1.gsfc.nasa.gov/images/thumbnails/2007-Jul-08_thumb.jpg http://cor1.gsfc.nasa.gov/images/movies/2007-May-15b.mpg A large CME off the northeast limb of the Sun detected on May 15, 2007, by both COR1-A and -B. http://cor1.gsfc.nasa.gov/images/thumbnails/2007-May-15b_thumb.jpg http://cor1.gsfc.nasa.gov/images/movies/cor1_lunar_transit_halfres.mpg 2007-02-24 The STEREO-B spacecraft was treated to a lunar transit of the solar disk. This is what the Moon looked like in the COR1 coronagraph as it headed toward the Sun and onward the following day. http://cor1.gsfc.nasa.gov/images/thumbnails/cor1_lunar_transit_thumb.jpg http://cor1.gsfc.nasa.gov/images/movies/20070124_FullRes.avi 2007-01-24 COR1-B North-East Quadrant showing CME at full spatial resolution in polarized brightness (pB) http://cor1.gsfc.nasa.gov/images/gallery_images/I1.jpg http://cor1.gsfc.nasa.gov/images/movies/20070124B.avi 2007-01-24 COR1-B full-field images showing CME in polarized brightness (pB) http://cor1.gsfc.nasa.gov/images/gallery_images/I2.jpg http://cor1.gsfc.nasa.gov/images/movies/20070503COR1AB_pB256.avi 2007-05-03 COR1-A and COR1-B polarized brightness (pB) movies showing Mercury passage when spacecraft were separated by 6.3 degrees http://cor1.gsfc.nasa.gov/images/gallery_images/I3.jpg http://cor1.gsfc.nasa.gov/images/movies/20070501_FullRes.avi 2007-05-01 COR1-B North-East Quadrant showing CME at full spatial resolution in polarized brightness (pB) http://cor1.gsfc.nasa.gov/images/gallery_images/I4.jpg http://cor1.gsfc.nasa.gov/images/movies/analysis_techniques.gif A comparison of various methods of studying CMEs From top to bottom, left top right: the polarized brightness movie; the same data, but with the first frame used as a base difference; the same data, this time with the previous frame subtracted (running difference); the wavelet decomposed (atrous wavelet, scale 2) of the same data (25 January 2007, COR1-B). http://cor1.gsfc.nasa.gov/images/gallery_images/movie_3.gif http://cor1.gsfc.nasa.gov/images/movies/gradient_modulus.gif The canny decomposition runs a 'Mexican hat' wavelet in each direction and then creates the modulus (plotted here) and the angle of maximum gradient (25 January 2007, COR1-B). http://cor1.gsfc.nasa.gov/images/gallery_images/movie_2.gif http://cor1.gsfc.nasa.gov/images/movies/gradient_direction.gif Angle of maximum gradient, in degrees clockwise from pointing right (black): up is red; left is green; down is blue (25 January 2007, COR1-B). http://cor1.gsfc.nasa.gov/images/gallery_images/movie_1.gif http://cor1.gsfc.nasa.gov/images/gallery_images/20070124_COR1B_animated.gif 2007-01-24 Polarized Brightness images from COR1-B (click on images for larger image) http://cor1.gsfc.nasa.gov/images/gallery_images/20070124_1413_COR1B_pB.jpg http://cor1.gsfc.nasa.gov/images/gallery_images/20070125_COR1B_animated.gif 2007-01-25 Polarized Brightness images from COR1-B (click on images for larger image) http://cor1.gsfc.nasa.gov/images/gallery_images/20070124_1413_COR1B_pB.jpg
