COR 1 Instrument
MOVIE GALLERY
- Prominence Eruption on April 9, 2008
- It is a combination of COR1A and SECCHI EUVI 304 Angstrom images showing a spectacular prominence eruption on 2008-04-09. This event was also seen by the Hinode soft X-ray imager, and joint analysis of this interesting event is underway.
- Jupiter System Spotted by COR 1 - November 29, 2007
- Jupiter entered the field of view of the COR1 telescope on the STEREO Ahead spacecraft on November 29th, 2007. Along with the planet itself, one can clearly make out some of the major Jovian moons. The first moons to enter the COR1 field are Ganymede and Callisto, which start out very close to each other. These are followed closely by Jupiter itself, which is heavily saturated in the COR1 images. As time progresses, and the moons revolve about Jupiter, Ganymede and Callisto separate from each other, and become visible as separate moons. One also sees Io and Europa come out from in front of Jupiter, so that there's a period when all four major moons are visible. Io is the hardest of the four moons to see, because it spends much of its time very close to Europa. The feature on the right side of the movie is the occulter which is used to block out the bright sunlight.
- CME - August 1, 2007
- A CME appears in the NE on August 1, 2007, as seen by EUVI and COR1. The image processing software that produced this movie and some others in the Gallery is "Festival" which is available at: http://www.ias.u-psud.fr/stereo/festival

- Combined data from EUVI and COR1 showing the lunar transit on 02/24/2007

- A CME seen by STEREO A & B and SOHO
- This movie show a CME lifting off the East limb as seen simultaneously by STEREOB (left), SOHO (center) and STEREOA (right).
- Sungrazer Comet in 3D
- The measured 3D position of the comet tail is overplotted in anaglyph format. Use red-blue glasses to see the effect.
- Sungrazer Comet Approaching the Sun
- This movie shows a sungrazer comet approaching the Sun as seen by the COR1 Ahead telescope on June 8, 2007. 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.
- An unusual event observed by STEREO
- 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!
- Wavelet-enhanced images
- Wavelet-enhanced images from May 2007, taken every six hours from COR1-A and COR1-B.
- June 2007 from COR1-A
- Assembled and image-processed using a wavelet enhancement technique by Dr. Guillermo Stenborg. The frames are four images per day for the month of June 2007 from COR1-A.
- Halo CME
- The COR1 coronagraph instrument on STEREO caught a nice "halo" CME (coronal mass ejection) as it expanded out into space on July 30, 2007. 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.
- An apparent "halo" CME
- An apparent "halo" CME detected in Total Brightness on 20-May-2007
- TotalB Movie
- TotalB movie of a multipart CME(s) on the West limb on 22-May-2007
- COR1 detection of a CME off the SE limb
- 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.
- A large CME off the northeast limb
- A large CME off the northeast limb of the Sun detected on May 15, 2007, by both COR1-A and -B.
- 2007-02-24 Lunar Transit
- 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.

- Comparing various methods of studying CMEs
- 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).
- The multiscale canny decomposed data
- 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).
- Angle of maximum gradient
- 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).
