Bülletään

Solar activity is extremely low without any flaring activity reported during last 24 hours. We do not expect any change of the activity in the coming hours. Coronagraph images do not show signatures of the Earth directed CMEs, and the solar protons are at the background level.

Solar wind speed has increased and it presently amounts about 510 km/s. The maximum solar wind speed (about 550 km/s), during last 24 hours was reached at about 11:20 UT today. The interplanetary magnetic filed magnitude is presently about 8 nT. The patchy but rather extended equatorial coronal hole (possibly even connected with the southern polar coronal hole), has reached central meridian early this morning. The associated fast solar wind is expected at the Earth in the mid of the day on July 24. The geomagnetic conditions are presently unsettled to quiet and we expect such a geomagnetic conditions to persist in the coming hours.
