Bülletään

Over the past 24 hours solar activity has been very low. No significant flares have been recorded. All Active Regions (AR) have shown low levels of activity. AR 2524 (Macintosh class:Eso; Mag. type:Beta) produced the largest flare, a B3.3 class flare peaking at 17:02 UT on 24-Mar-2016, which had a very small eruption associated with it. AR 2526 recently rotated over the East limb, but due to its proximity to the limb it is still difficult to ascertain the magnetic complexity of the region, however it produced a couple of B-class flares yesterday and may have the potential for further activity. No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 hours. Solar activity is expected to remain low over the next 24 hours with a reasonable probability of C-class flares and a low probability of M-class flares.

The solar wind speed has been slowly increasing from around 450 to 550 km/s over the past 24 hours. The total magnetic field strength has fluctuated between around 5 and 10 nT, peaking at 14:00 UT yesterday. The Bz component was largely positive, fluctuating between -4 and +5 nT. Geomagnetic conditions ranged between Kp index 1-3 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. There is currently a positive polarity Northern polar coronal hole with a large extension to lower latitudes near disk center, as this region rotates further into the Western hemisphere the resulting high-speed stream (HSS) should enhance solar wind speeds at the Earth and as a consequence may increase geo-activity levels in the next 24 to 48 hours.
