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.

            "description": "Magnetic field lines dance above the surface of the sun. Called coronal loops, these lines are difficult to observe from afar, since they are invisible. Scientists can observe them in two ways: by watching the visible solar material that flows along the lines or by modeling them using computer simulations. Studying these formations help us understand the way energy travels on and around the sun. The Solar and Heliospheric Observatory, or SOHO, is a sun-observing spacecraft that can measure and depict distortions in the sun’s magnetic field. Using data collected by the spacecraft, scientists created a virtual, 3D model of the field lines. Watch the video to explore the loops. || ",

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. || ",

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. || ",

At this time the spacecraft were about 3.7 degrees apart. These images show the Sun in extreme ultraviolet light at a wavelength of 171 angstroms, highlighting parts of the Sun's atmosphere (the corona) at about one million degrees C. Note the bright active regions near the Sun's equator and the dark \"coronal holes\" at the north and south poles. These are features of the Sun's magnetic field. Coronal holes are areas where the magnetic field opens out to allow material to flow out into the solar system, while active regions are made up of strong, closed fields which bottle up hot plasma (ionized gas) close to the surface. This image was taken near the minimum in solar activity, so there are few active regions.Closeup View: Image sequences taken April 8-9, 2007 by the EUVI telescopes in the SECCHI imaging suites on the two STEREO spacecraft (STEREO-B, left eye; STEREO-A, right eye). At this time the spacecraft were about 3.7 degrees apart. Here we see a close up of solar magnetic active regions, flickering as they rotate out of sight around the sun. These are areas where the Sun's strong magnetic field bottles up million degree C plasma (ionized gas) low in the corona (the Sun's outer atmosphere). These images are taken at a wavelength of 171 angstroms (0.00000171 cm) in the extreme ultraviolet.Note for Large Displays: These movies are produced using images from STEREO where the angle between the spacecraft is getting larger than the optimum angle for stereo separation. While they work well on small displays, large-screens and projection systems can introduce significant distortions in the stereo effect which the audience may find uncomfortable. When doing large-screen projection, you may need to adjust the left-right image alignment for optimum viewing. However, this does not guarantee a distortion-free result. || ",

            "description": "This movie collects imagery from SOHO and STEREO-A of a coronal mass ejection (CME) during January of 2007. The instruments in this view, from left to right, are STEREO/HI-1, STEREO/HI-2, SOHO/LASCO/C3, SOHO/LASCO/C2, and STEREO/EUVI. The Heliospheric Imager, HI-2, shows some of the tail of comet McNaught. The dark trapezoidal shape on the left edge of the image in HI-2 is the Earth occulter which will block out the disk of the Earth when it moves into view (since the planet will appear so bright as to saturate the detectors). Due to ongoing work with the STEREO coronagraphs, COR1 and COR2, the SOHO/LASCO coronagraphs are used for this movie. The blue Sun in the center of the coronagraphs is STEREO/EUVI ultraviolet images.There is a 22 hour gap in the data coverage for HI-2 which creates the appearance of a jump in the playback.These are not standard images but are called 'running difference' images which highlight changes in the view. White pixels correspond to increases in brightness, while dark pixels reflect a decrease in brightness, with respect to the immediately previous image.'Running differencing' generates some unusual effects. For example, the mottled background is created by the motion of the stars through the field-of-view as the spacecraft pointing direction slowly changes (the Andromeda galaxy is the oblong 'smudge' near the upper left corner). The planets Venus (right edge of HI-2) and Mercury are visible (near center of HI-1), their column of pixels saturated due to their brightness.STEREO: Solar TErrestrial RElations ObservatorySOHO: SOlar Heliospheric ObservatoryLASCO: Large Angle and Spectrometric CoronagraphEUVI: Extreme UltraViolet Imager || ",

The resulting magnetogram is then processed through the Potential Field Source Surface (PFSS) model which constructs the magnetic field above the solar surface. The magnetic field around the Sun is then analyzed for field lines, which creates the loop structures we see in the model. Hot plasma tends to flow along the magnetic field lines, creating the coronal loops. These loops are only visible at the higher temperatures corresponding to ultraviolet light, in this case, 195 angstroms, one of the filter wavelengths of SOHO/EIT.
