There is only one active region presently observed on the visible side of the solar disc, NOAA AR 2766. This newly emerged region is potential source of the B-class flares in the coming hours, while C-class flares are possible but not very probable. The eruption from the NOAA AR 2766 observed at about 05:00 UT this morning was associated with the coronal dimming (on disc signature of the CME) indicating possibly associated CME. As the NOAA AR 2766 is presently situated on the center of the solar disc, the CME from this region would be Earth-directed. More will be reported later when more observations will be available. During last 24 hours solar protons have remained at background level.

The in situ observations indicate arrival of the fast solar wind associated with the low latitude extension of the northern polar coronal hole (positive polarity) that started its passage across the central meridian in the afternoon of July 01. At about 15:00 UT on July 04 the interplanetary magnetic field (IMF) magnitude started to increase simultaneously with the increase of the solar wind speed and temperature. During the passage of the compression region between the slow and fast solar wind the IMF reached its maximum value of 11 nT. The solar wind speed is presently 500 km/s and the IMF magnitude is about 5 nT. Due to intervals of the negative value of the Bz component (down to -8 nT), unsettled geomagnetic conditions were reported before midnight on July 4 and after 09:00 UT this morning (local station at Dourbes reported interval with K=3 and NOAA reported interval of Kp=3). The geomagnetic conditions are presently unsettled and we expect quiet to unsettled geomagnetic conditions in the coming hours.
