Bülletään

Over the past 24 hours solar activity has been low, there have been no C-class or M-class flares recorded. NOAA Active Region (AR) 2452 (Axx/alpha) rotated into view and was numbered, it appears quite stable. All other regions have remained stable with little flux emergence. There were no Earth directed Coronal Mass Ejections (CMEs) observed in the past 24 hours. The solar wind speed has steadily declined over the past 24 hours, from 650 km /s to around 500 km /s. The total magnetic field has fluctuated between 2 and 5 nT and the Bz component has oscillated between -4 nT and +4 nT. Geomagnetic conditions ranged between quiet and active over the past 24 hours (NOAA Kp 1-5, local K Dourbes 0-4). Geo-activity reached storm levels (Kp 5) around 18:00 UT yesterday (2015-Nov-11), which was possibly caused by the trailing edge of the High Speed Stream (HSS) or a glancing blow from the CME generated on 2015-Nov-09.
