Over the past 24 hours solar activity has been low. Several C-class flares have been detected. The most energetic flares were C1.4 class flares, produced by NOAA Active Region (AR) 2488. There is currently a large polar coronal hole rotating into the Western hemisphere which may increase geo-activity over the coming days. No Earth directed Coronal Mass Ejections (CMEs) have been detected. A currently unnamed region on the East solar limb produced a small CME around 12:00 UT yesterday (24-Jan-2016), the CME is not believed to be geo-effective. Solar activity is expected to remain low over the next 24 hours with the possibility of C-class flares, and the small region on the East limb producing further eruptions. The solar wind speed has been steadily decreasing over the past 24 hours from 500 km/s to 410 km/s. The total magnetic field strength remained around 5 nT. However, it peaked around 8 nT between 17:00 and 19:00 UT yesterday. The Bz has remained around 0 nT, but also fluctuated between 17:00 and 19:00 UT, reaching values of +5 and -5 nT. Geomagnetic conditions ranged between Kp index 1-4 (NOAA) and local K index 0-4 (Dourbes) over the past 24 hours, with activity peaking (Kp = 4; K =4) around 19:00 UT, coinciding with the fluctuating field. A low latitude section of a large polar coronal hole has rotated into the Western hemisphere and the resulting high-speed stream (HSS) may enhance solar wind speeds and increase geo-activity early tomorrow morning.
