Bülten

Solar activity is low and there were no even B-class flares reported during last 24 hours. We expect such a low flaring activity to persist in the coming hours. Coronagraph images do not show signatures of the Earth directed CMEs, and the solar protons are at the background level.

The in situ observations indicate arrival of the possible ICME. The increase of the interplanetary magnetic field magnitude (up to 15 nT), observed at about 20 UT on July 16, was followed by rotation of the magnetic field phi angle, increase of the solar wind speed and temperature, and decrease of the density. Solar counterpart of this structure is presently unclear, and one of the possibility is the large prominence eruption from the south-west quadrant of the Sun, observed on July 13 at about 22 UT. The solar wind speed is presently about 420 km/s and the interplanetary magnetic field magnitude is about 6 nT. The increase of the solar wind speed, associated with patchy equatorial coronal hole which reached central meridian on July 16, is expected at the Earth late on July 19. Due to longer interval of the negative value of the Bz component of the interplanetary magnetic field (down to -5nT) local station at Dourbes reported slightly disturbed geomagnetic conditions o (K=4) at about 21 UT on July 16, and NOAA reported value of the Kp=3. The geomagnetic conditions are presently quiet, and we expect quiet geomagnetic conditions to persist in the coming hours.
