Bulletin
Solar activity has been very low, no C-class flares in past 24 h. An active region about to rotate into view (seen by STEREO-A) may increase the activity in the coming hours.
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 350 km/s with interplanetary magnetic field of 4 nT. The high speed stream that was expected to arrive seems to have missed the Earth. Geomagnetic conditions are quiet and expected to remain so.
