om Earth, the most sunward boundary position is called the magnetopause stand-off position.
AS can be seen in the GIF below at around the 01:00 UTC (Apr 10) the computed distance of the magnetopause stand-off was cleary blown away from the Earth. Blassted with both magnetons and electrons from the side and from behind pushing the magnetopause towards the direction of the Sun. Noted in the chart topping Magnetopause StandOff Distance of 16+ RE.

"Normally, Earth’s magnetosphere extends out a distance of approximately 10 Earth radii toward the Sun and several hundred Earth radii away from the Sun. This is because the Sun’s particle flow compresses the side of Earth’s magnetic field that is facing the Sun and elongates Earth’s magnetic field that faces away. Earth’s magnetic field is actually contained within an inner layer of the magnetosphere called the magnetopause."

Distances in the magnetosphere are often measured in Earth radii (RE), with one Earth radius amounting to 6371 km or 3960 miles. In these units, the distance from the Earth's center to the "nose" of the magnetosphere is about 10.5 RE and to the flanks abreast of the Earth about 15 RE, while the radius of the distant tail is 25-30 RE. By way of comparison, the moon's average distance is about 60 RE
