Also the Rain

The stack crossed Mercury’s field during a solar particle event it did not seek.

Outside: hard flux. Inside: a drop — cavity carved by a field one percent of Earth’s, no atmosphere to finish the work.

Shield is a late mouth. Leftover is the drop and the rain: most deflected; a fraction still finds bare rock along open lines, the offset dipole, the dayside pressed to crust.

Prague zataženo, rain from the northwest, about sixteen; sunset already nineteen twenty-one. The cavity holds most. The rest strikes stone.
