Bülletään

The visible side of the Sun remains to be spotless and consequently, there is no flaring activity reported during last 24 hours. We expect such a low flaring activity to persist in the coming hours. No Earth directed CMEs were observed, and the solar protons remained at the background level.

The solar wind speed is presently about 450 km/s and the interplanetary magnetic field magnitude is about 5 nT. It is presently unclear if the small increase of the solar wind speed (up to 480 km/s was reached at 09 UT this morning), and interplanetary magnetic field (up to 7 nT), are due to a structure in the slow solar wind or a solar wind flow associated with patchy equatorial coronal hole (reached central meridian on July 16). The geomagnetic conditions are presently unsettled to quiet and we expect such a geomagnetic conditions to persist in the coming hours.
