Anaglyph image set still under development...
Image artifact issues
There are a few instrument issues in this run as it includes frames collected from calibration
The 193/195 filter set, for July 6, 2023 around 22:00 - 22:20 TAI (frames 2230-2250) exhibit some brightness changes due to AIA calibration testing.
The 304 filter set, for July 12, 2023 around 17:45 - 20:05 TAI (frames 1350-1370) exhibit some image shifts due to a calibration test for the EVE instrument.

"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. || ",

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.",
