Bülletään

Solar activity has remained quiet over the past 24 hours with no significant flares. AR 2381 has produced the largest flare, a B7.4 class flare, peaking at 09:15 UT on 2015-Jul-05. There are some flows / small eruptions emerging from beyond the north-east solar limb, and when the source region rotates into view we may see an increase in activity. The proton numbers have continued to be low and have not exceeded 1 pfu at the Earth in the past 24 hours. The solar wind speed increased from approx. 320 km / s to 500 km / s over the past 24 hours, peaking at approx. 600 km / s at 20:00 UT on 2015-Jul-04. The total magnetic field has fluctuated and reached approx. 20 nT at 18:00 UT on 2015-Jul-04 and has subsequently declined to around 10 nT. The Bz reached approx. -20 nT at 20:00 UT. These solar wind conditions caused an ongoing geomagnetic storm, Kp (NOAA) reached 6 in the period from 18:00 to 6:00 UT and has subsequently dropped to 5, the local K (Dourbes) is currently at 4. Enhanced geomagnetic storm conditions are expected to continue for a couple of days due to the presence of a coronal hole in the south west generating a high speed stream.
