Bülletään

The active region visible on the solar disc, NOAA 2723 with beta magnetic field configuration, is slowly decaying. No C-class flares in past 24 h. Solar activity is expected to remain at low levels.

No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 hours.

The solar wind speed is at 410 km/s with interplanetary magnetic fields of 5 nT. Geomagnetic conditions have been quiet to unsettled. The fast solar wind associated with a small negative polarity equatorial coronal hole influenced the Earth overnight, but caused only unsettled conditions (Kp = 3 and K at Dourbes = 3) with speeds slightly above 500 km/s and interplanetary magnetic field reaching 10 nT. Quiet conditions expected for the next 48 h. The fast solar wind associated with a positive polarity coronal hole will arrive to the Earth on October 7-8, causing disturbed geomagnetic conditions.
