See also STEREO-A Returns by Earth.While STEREO-B is no longer available, it is possible to construct stereo imagery of the Sun using STEREO-A with Solar Dynamics Observatory (SDO).  Here we present a series of images for corresponding filters between the two missions which can be used for stereo viewing.Color (SDO color table) Left/Right Image PairsIn this section, we present frame-synchronized left eye (STEREO-A) and right eye (SDO) for the specified ultraviolet filter.  They are provided as separate movie and frame-sets to maximize flexibility for the target viewing technology.  Time stamps are provided as separate image files for compositing if desired.   If you match frame numbers for the image sets for a specific filter, you will have images closest in time for apropriate left/right eye pairing.171 Angstrom filter || ",

            "description": "On July 23, 2012, a massive cloud of solar material erupted off the sun's right side, zooming out into space. It soon passed one of NASA's Solar Terrestrial Relations Observatory, or STEREO, spacecraft, which clocked the CME as traveling between 1,800 and 2,200 miles per second as it left the sun. This was the fastest CME ever observed by STEREO.  Two other observatories – NASA's Solar Dynamics Observatory and the joint European Space Agency/NASA Solar and Heliospheric Observatory — witnessed the eruption as well. The July 2012 CME didn't move toward Earth, but watching an unusually strong CME like this gives scientists an opportunity to observe how these events originate and travel through space.  STEREO's unique viewpoint from the sides of the sun combined with the other two observatories watching from closer to Earth helped scientists create models of the entire July 2012 event. They learned that an earlier, smaller CME helped clear the path for the larger event, thus contributing to its unusual speed. Such data helps advance our understanding of what causes CMEs and improves modeling of similar CMEs that could be Earth-directed. || ",

            "description": "STEREO-A, at a position along Earth's orbit where it has an unobstructed view of the far side of the Sun, could clearly observe possibly the most powerful coronal mass ejection (CME) of solar cyle 24 on July 23, 2012.  The visualizations on this page cover the entire day.We see the flare erupt in the lower right quadrant of the solar disk from a large active region.  The material is launched into space in a direction towards STEREO-A.  This creates the ring-like 'halo' CME visible in the STEREO-A coronagraph, COR-2 (blue circular image).As the CME expands beyond the field of view of the COR-2 imager, the high energy particles reach STEREO-A, creating the snow-like noise in the image.  The particles also strike the HI-2 imager (blue square) brightening the image.The HI-1 imager has had 'bloom removal' enabled and filled with contents of the immediately previous HI-1 image, which creates a linear artifact above and below bright stars and planets. || ",

The movie was made by combining nearly simultaneous view of the Sun from three spacecraft: STEREO AHEAD and BEHIND (seeing the Sun's far side) and the Solar Dynamic Observer (seeing the near side). This EUV light comes primarily from the solar chromosphere.  The bright patches are active regions. Many dark prominence eruptions can also be seen. The data is plotted in Carrington coordinates which are \"fixed\" to the surface of the Sun. In this coordinate system, the active regions tend to stay at the same location.  However, the Sun's rotation rate actually changes with latitude and this can be seen in the movie. || ",

This eruption, called a coronal mass ejection, or CME, sent plasma streaming out through the solar system. STEREO has an extreme ultraviolet camera similar to the Solar Dynamics Observatory (SDO) satellite, but it also has coronagraph telescopes like the European Space Agency/NASA Solar and Heliospheric Observatory (SOHO) where the bright sun is blocked by a disk so it does not overpower the fainter solar atmosphere. As a result, using its two inner coronagraphs, STEREO was able to track the CME from the solar surface out to 6.3 million miles. || ",

            "description": "This is a sequence of 4Kx2K images, cylindrical-equidistant projection, of the Sun that can be mapped to a sphere. The sequence was assembled by combining 304 Ångstrom (extreme ultraviolet wavelength) images from STEREO-A, STEREO-B, and the Solar Dynamics Observatory (SDO). The series covers the time frame shortly after the STEREO spacecraft moved into a position where they had a complete view of the side of the Sun not visible from the Earth (see Sun 360).Technical DetailsThe data are sampled in time approximately every three hours. Since each spacecraft is at a slightly different distance from the Sun, the intensity received by each pixel was normalized to correspond to the intensity one astronomical unit from the Sun using the inverse-square law. The flux was also adjusted for the fact that each pixel captures a different fraction of the light due to their different angular size for each spacecraft. The image from each spacecraft is then reprojected using the World Coordinate System (WCS) routines of the SolarSoft library. Masks were made to smooth the transition where datasets overlap. There are a few gaps in the data, especially near the poles of the Sun, that are filled using data from the previous time step.Note: This sequence is suitable for animation and visualization purposes but NOT for scientific analysis. || ",

Combined with solar observing satellites near the Earth, such as SDO and SOHO, this coverage will last for about eight years and the STEREO spacecraft move along in their orbits.This movie illustrates the orbital motions of the two STEREO spacecraft relative to the Earth (and noting the positions of the planets Mercury & Venus for reference). The camera occupies a position fixed relative to the Earth and Sun, so the distant starfield appears to spin around the observer. Because the frames are sampled at one per solar day, the Earth does not appear to rotate, but patient observation reveals that the tilt of the planet relative to the Sun, varies throughout the year, with the northern hemisphere tilted towards the Sun in northern hemisphere summer and away from the Sun in northern hemisphere winter. || ",

Combined with solar observing satellites near the Earth, such as SDO and SOHO, this coverage will last for about eight years and the STEREO spacecraft move along in their orbits.In this movie, we zoom in towards the Sun, fading from a visible light view to data from the 304 Ångstrom filters aboard SDO and both STEREO spacecraft. We swing the camera around to a view of the side of the Sun NOT visible from the Earth. With the STEREO and SDO data mapped to the sphere representing the Sun, we see the dark sliver of \"No Data\" which slowly shrinks as the STEREO spacecraft move into position 180 degrees apart on opposite sides of the Sun (and 90 degrees from Earth). STEREO data near the edge of the solar disk get stretched when projected onto a sphere and is responsible for the streaking on either side of the dark sliver. These data are sampled roughly six hours apart for each frame of the movie. Slight differenences in the six hour time step creates a slight 'jitter' of the dark sliver. || ",
