Bülletään

Over the past 24 hours solar activity has been low. The visible solar disc was spotless and the X-ray flux remained below B-class level. 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. Solar activity is expected to remain low over the next 24 hours.

The solar wind speed has fluctuated between 355 and 450 km/s over the past 24 hours. The total magnetic field strength fluctuated around 5 nT for much of the period, with a minimum of 0.6 nT and a maximum of 7.1 nT recorded. The Bz component was predominantly positive and ranged between -4.8 and +7.1 nT.

Geomagnetic conditions have been quiet to unsettled over the past 24 hours, with Kp index (NOAA) and local K index (Dourbes) ranging between 1-2 and 1-3, respectively. Quiet to unsettled geomagnetic conditions are expected to continue over the next 24 hours, due to the weak solar wind stream associated with the patchy negative polarity equatorial coronal hole which began to traverse the central meridian on 18 May.
