Positions of STEREO A and B for 2-May-2026 04:00 UT

This figure plots the current positions of the STEREO Ahead (red) and Behind
(blue) spacecraft relative to the Sun (yellow) and Earth (green). The dotted
lines show the angular displacement from the Sun. Units are in A.U.
When the two spacecraft are close to Earth, an expanded view of the region
around Earth will appear on the right, in the same orientation as the
Sun-centered view.
