Bulletin

Solar activity remains to be at very low level, and there were no flares reported during last 24 hours. As there are no active regions present at the visible side of the Sun, we expect such a low flaring activity to persist in the coming hours. No Earth directed CMEs were observed during last 24 hours, and the solar protons remained at the background level.

The increase of the solar wind speed, associated with patchy equatorial coronal hole that reached central meridian on July 16, is expected at the Earth late on July 19. The unsettled to possibly, but not very probably, active conditions are expected in the morning of July 20, due to the expected arrival of the fast solar wind. The geomagnetic conditions are presently quiet, and we expect them to stay so in the coming hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 22 stations.
