Solar activity has been low, one C-class flare in past 24 h (C1.0), produced by NOAA AR 2665 (the only visible AR on the disk) with peak at 13:49 UT on 7 July. This region has grown considerably in the past hours, more C-class flares can be expected (and less likely M-flares).
No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 hours.
Solar wind speed is at 340 km/s with interplanetary magnetic field of 3 nT. Geomagnetic conditions have been quiet quiet. The high speed stream from the equatorial coronal hole is expected to arrive today, geomagnetic conditions can go up to the minor storm level (with isolated moderated storm periods possible, k = 6).
