About the STEREO Ahead (A) Satellite...

This diagram below plots the current positions of the STEREO Ahead ((A) red) and Behind ((B) blue) spacecraft relative to the Sun (yellow) and Earth (green). The dotted lines show the angular displacement from the Sun. Units are in Astronomical Units... STEREO consists of two space-based observatories - one ahead of Earth in its orbit, the other trailing behind. With this pair of viewpoints, scientists are able to see the structure and evolution of solar storms as they blast from the Sun and move out through space. Communications with Stereo B were lost back in 2016 so no images are available from this satellite...
