Bülten

During last 24 hours solar activity was very low with only two B-class flares reported. As the visible side of the solar disc is presently spotless we do not expect flaring activity in the coming hours. Presently available 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 structure in the slow solar wind, of presently unclear solar origin. Early this morning interplanetary magnetic field started to increased (it reached the value of about 10 nT) following, with of about 10 hours of the delay, the increase of the density and drop of the temperature. The solar wind speed reached its maximum value (during last 24 hours) of about 340 km/s early this morning. The present value of the solar wind speed is 320 km/s and the interplanetary magnetic field magnitude is about 8 nT. Very patchy equatorial coronal hole, which seem to be connected to the low latitude extension of the northern polar coronal hole, has reached central meridian this morning. The increase of the solar wind speed, associated with this coronal hole is expected late on July 19. Due to longer interval of the negative value of the Bz component of the interplanetary magnetic field (down to -8 nT) local station at Dourbes reported disturbed geomagnetic conditions at about 09 UT today (K=4), and NOAA reported value of the Kp=3. The geomagnetic conditions are presently quiet to unsettled, and we expect quiet geomagnetic conditions to persist in the coming hours.
