This pageBlink 62 SPHEREx images of one patch of sky: stars hold still, anything that jumps is moving.
Survey tile in Capricornus
A 0.3 degree patch 0.8 degrees north of the ecliptic in Capricornus, imaged by SPHEREx 32 times in 13 visits over 52 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, 2.2 days 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.
