"description": "This visualization shows the dataset from STEREO-A processed to enhance the visibility of the coronal mass ejection (CME) in entry #3846. The data are combined from the SECCHI instrument, which includes an ultraviolet image of the Sun (EUVI), two coronographs (COR-1 & COR-2), and the wide-angle Heliospheric Imagers (HI-1 & HI-2).Because the enhancement process for the CME involves computing differences from a number of sequential HI-1 and HI-2 images, the Earth (left side) and Venus (middle) are masked and oversized icons are installed to mark their position. The dark shape on the left of the field of view is created by an occulting tab that was installed to (occasionally) hide the bright Earth in the view.The little cross markers label three other planets in the view of STEREO. Uranus is almost invisible in the scale of this imagery, but is visible in full-resolution datasets. || ",

"title": "STEREO-A Returns by Earth",
"description": "The Solar Terrestrial Relations Observatory (STEREO) mission was launched on October 25, 2006, with the purpose of tracing the flow of energy and matter from the Sun to Earth. The STEREO mission began with two spacecraft: STEREO-A and STEREO-B. Each was launched into Sun-orbiting trajectories - STEREO-A moving ahead of Earth, and STEREO-B moving behind Earth (STEREO's Routes to Solar Orbits). In mid-August 2023, the still-operational STEREO-A (STEREO-B went offline in October 2014) will pass Earth for the first time since its launch 17 years ago. Like race cars driving different speeds around a circular track, STEREO-A is traveling slightly faster than Earth around the Sun. After launch, STEREO-A pulled ahead of Earth and extended its lead a little bit more with each orbit. Now, STEREO-A’s lead is so great that it is catching up to Earth from behind and is about to “lap” Earth, having completed 18 circuits around the Sun while Earth completed just 17. || ",

"alt_text": "A view of the orbit of STEREO-A relative to Earth from mid-June 2023 to mid-October 2023, as it passes Earth. The camera is anchored on the Earth-Sun line so Earth and the Sun appear fixed while the distant stars appear to move around the camera. This movie starts with a wide view of the inner solar system with STEREO-A and Earth marked. The camera then zooms in to a closer view of Earth showing Solar Dynamics Observatory (SDO) orbiting Earth, the heliophysics missions orbiting the L1 Lagrange Point (the green cross), and the orbit of the Moon.",

"title": "From the Sun to the Earth: The View from STEREO-A with no CME Enhancement",
"description": "This visualization shows the original dataset from STEREO-A used to extract the motion of the coronal mass ejection (CME) in ID 3890. The data are combined from the SECCHI instrument, which includes an ultraviolet image of the Sun (EUVI), two coronographs (COR-1 & COR-2), and the wide-angle Heliospheric Imagers (HI-1 & HI-2).On this scale, the CME is so faint as to be invisible. However, the Heliospheric Imagers support such a broad range of image intensity that it is possible to observe the CME propagating through the field of view by computing differences of images with the preceeding image. This process is shown in animation #3890.The Earth (left side) and Venus (middle) are so bright as to 'bloom' along the readout line of the CCD (Charge-coupled device) pixels, which creates the bright vertical lines that move slightly with time. The dark shape on the left of the field of view is created by an occulting tab that was installed to (occasionally) hide the bright Earth in the view.The little cross markers label three other planets in the view of STEREO. Uranus is almost invisible in the scale of this imagery, but is visible in full-resolution datasets. || ",

If you watch the bright 'bloom' created by the Earth (left side) starting around the December 28, 2008 time marker, you will see a much smaller, fainter 'bloom' appear between the Earth and the Sun. This is the Moon appearing at maximum elongation relative to the STEREO-A spacecraft.",
