This pageBlink 22 SPHEREx images of one patch of sky: stars hold still, anything that jumps is moving.
Survey tile in Gemini
A 0.3 degree patch 1.7 degrees north of the ecliptic in Gemini, imaged by SPHEREx 11 times in 3 visits over 13 hours. Picked automatically by the survey because it was imaged often enough to follow a moving object.

The same patch, with time as the third dimension
Stack every image of this patch in the order it was taken, 13 hours from bottom to top. A star sits at the same spot in each, so it would draw a vertical line. The moving object leans across the stack: each dot is one measured position, and the faint line on the floor is the path on the sky.
