Bülletään

Over the past 24 hours solar activity has been very low. No significant flares have been recorded. Active Region (AR) 2670 (Mcintosh class:Hsx; Mag. type:Alpha) has been quiet, but is now approaching the west solar limb. 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 with a low probability of C-class flares. The solar wind speed has remained around 575 km/s, with several short sporadic increases to speeds up to 750 km/s, over the past 24 hours. The total magnetic field strength has been decreasing from around 10 nT to 5 nT. The Bz component fluctuated around 0 nT but was mainly positive, ranging between -5 and +7 nT. Geomagnetic conditions ranged between Kp index 1-3 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. Several small low latitude coronal holes are currently in the Western hemisphere, and as a consequence there have been small increases in geomagnetic conditions. Geomagnetic conditions are expected to be mainly quiet with some short periods of activity.
