Abstract
Collisionless shock nonstationarity arising from microscale physics influences shock structure and
particle acceleration mechanisms. Nonstationarity has been difficult to quantify due to the small spatial and
temporal scales. We use the closely spaced (subgyroscale), high-time-resolution measurements from one
rapid crossing of Earth
