Over the past 24 hours solar activity has been very low. No significant flares have been recorded. All Active Regions (ARs) have shown low levels of activity, however AR 2629 (Mcintosh class:Cso; Mag. type:Beta) has shown some evidence of flux emergence and cancellation, which may increase flaring activity over the next couple of days. 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 and a very low probability of M-class flares. A large negative polarity trans-equatorial coronal hole extending from the Southern pole, has moved into the Western hemisphere. The solar wind speed has decreased from around 475 to 380 km/s over the past 24 hours, but jumped to around 450 km/s around 11:00 UT this morning. The total magnetic field strength has remained around 5 nT, but jumped to 7 nT at around 11.00 UT this morning. The Bz component fluctuated around 0 nT, ranging between -7 and +7 nT, and has been approaching -7 nT this morning. Geomagnetic conditions ranged between Kp index 1-2 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. The large negative polarity trans equatorial coronal hole extending from the Southern pole, will likely increase solar wind speeds at the Earth in the coming days. The associated Co-rotating Interaction Region (CIR) is likely to hit the Earth system today, and may be responsible for the increased solar wind speeds and magnetic field strengths experienced this morning. As a consequence Geomagnetic conditions are expected to increase from quiet to active conditions.
