There are no active regions, presently observed on the visible side of the solar disc, and accordingly solar flaring activity is very low. We expect such a low level of the solar activity, without C-class and even B-class flares, to persist in the coming hours. There were no wide and/or Earth directed CMEs reported and the solar protons remained at the background level.

At about 03:40 UT this morning, interplanetary magnetic field magnitude increased (to the value of about 14 nT) simultaneously with the increase of the solar wind speed and decrease of the temperature indicating arrival of possibly either ICME (still unclear what would be its solar counterpart) or a structure at the boundary between the slow and the fast solar wind. More will be reported later, when larger part of the structure becomes visible in the in situ observations. The solar wind speed is presently about 430 km/s and the interplanetary magnetic field magnitude is presently 9 nT. The fast solar wind associated with the negative polarity equatorial coronal hole which reached central meridian on March 25 is expected at the Earth tomorrow. The geomagnetic conditions are quiet to unsettled (both local station at Dourbes and NOAA reported only K=3 and Kp=3, respectively) and we expect them to stay so in the coming hours.
