Over the past 24 hours solar activity has been low with no active regions on the solar disk. No flares have been recorded. No Earth directed Coronal Mass Ejections (CMEs) have been detected. The greater than 10MeV proton flux remained at background levels over the past 24 hours. A low latitude negative polarity coronal hole has crossed the central meridian two days ago. Solar activity is expected to remain low over the next 24 hours. Only B-class flares can be expected. Solar wind parametrs variations have been very low. The solar wind speed is below 385 km/s. The total magnetic field strength has fluctuated between 2nT and 5nT. The Bz component has fluctuated between -3.5nT and +4nT. Geomagnetic conditions ranged between Kp index 0-2 (NOAA) and local K index 0-2 (Dourbes) over the past 24 hours. Mostly quiet geomagnetic levels are expected for the whole day. Unsettled and even active conditions can be expected from tomorrow due to the influences of a high speed stream coming from the low-latitude negative polarity coronal hole.
Today's estimated international sunspot number (ISN): 000, based on 22 stations.
