Bulletin

Over the past 24 hours solar activity has been very low. The largest flare was a C1.1 class flare. NOAA Active Region (AR) 2524 (Macintosh class:Eso; Mag. type:Beta) has been most active, producing the C1.1-class flare, which peaked at 03:54 UT. AR 2524 continues to show evidence of small amounts of flux emergence in HMI observations, which may result in further flaring activity. The above-mentioned C1.1-class flare had a small Coronal Mass Ejection (CME) associated with it, that travelled mainly to the North, and is not expected to interact with the Earth system. No Earth directed CMEs have been detected. Solar proton levels 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 400 and 450 km/s over the past 24 hours. The total magnetic field strength has fluctuated between 5 nT and 7 nT. The Bz component was largely positive yesterday, around 5 nT, but became negative between 03:00 and 07:00 UT this morning and has fluctuated between -5 and +5 nT since then. Geomagnetic conditions ranged between Kp index 2-4 (NOAA) and local K index 2-3 (Dourbes) over the past 24 hours, with the negative Bz creating Kp = 4 conditions. There is currently a large Northern polar coronal hole that has a small extension to lower latitudes, this may enhance solar wind speeds at the Earth over the coming days. However, the Northern polar coronal hole also has a large extension to lower latitudes in the Eastern hemisphere, which will increase solar wind speeds in a few days.
