Bulletin

Over the past 24 hours solar activity has been quiet. No significant flares have been recorded. No Earth directed Coronal Mass Ejections (CMEs) have been detected. There are no significant filaments. Solar activity is expected to remain low over the next 24 hours with a low probability of C-class flares. The solar wind speed has fluctuated between 510 and 580 km/s over the past 24 hours. The total magnetic field strength has fluctuated around 5 nT. The Bz component has fluctuated around 0 nT, between -6.3 and +5.3 nT. Mostly unsettled to active geomagnetic conditions have been observed, with Kp recording an isolated minor storm episode during the 00-03UT interval this morning (14 September). Mostly unsettled geomagnetic conditions are expected for the next two days due to possible intremittent Earth interaction with the eleveated solar wind sterams coming from the positive polarity coronal hole. Active conditions can be expected as well on the day three (16 September) due to the influence of another neagtive polarity coronal hole.

Today's estimated international sunspot number (ISN): 000, based on 21 stations.
