Bulletin

Over the past 24 hours solar activity has been low. The largest flare was a B4.6 class flare, produced by Active Region (AR) 2528 (Macintosh class:Bxo; Mag. type:Beta), which peaked at 07:37 UT this morning. This AR 2528 is currently the only significant region on disk with evidence of small amounts of flux cancellation in HMI magnetogram observations. There are two other ARs 2527 and AR 2526 (Hsx; Alpha), and 2526 has moved onto the West limb. 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 low probability of C-class flares. The solar wind speed has fluctuated between 350 to 450 km/s over the past 24 hours. The total magnetic field strength remained stable with the magnitude varying between 6 and 8 nT. The Bz component remained around 0 nT, varying between +9 and -7 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 small coronal hole on disk. Geomagnetic activity is expected to remain low within next 2 days.
