Over the past 24 hours solar activity has been low. The largest flare was a B7.7 class flare, produced by Active Region (AR) 2529 (Macintosh class:Hkx; Mag. Type:Alpha), which peaked yesterday at 13:37 UT. This AR 2528 is currently the only significant region on disk with evidence of small amounts of flux cancellation in HMI magnetogram observations. Another AR 2528 (Macintosh class:Cao; Mag. Type:Beta), is moving onto the West limb. A Coronal Mass Ejection(CME) detected yesterday at 08:36 UT originated at the West Limb has some probability to hit the Earth in approximately 3 days time. The initial median speed of CME is 450 km/s, which is higher than the background median solar wind speed 400 km/s. 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 parameters have been affected by the sector boundary crossing from 17:30 UT 07-Apr-16 till 04:00 UT today. The total magnetic field strength in solar wind has increased till 14 nT, while Bz component of the magnetic field decreased till -14 nT simultaneously with the transition of the Phi angle. The solar wind speed however remained stable varying around 400 km/s over the past 24 hours. As the consequence a minor magnetic storm has occurred detected at 24:00 UT today, which lasted approximately till 08:00 UT today. Geomagnetic indexes as detected this morning (Kp index = 5 (NOAA), local K index = 6 (Dourbes) at and Dst Kioto = 72 nT) are returning to the quiet unperturbed conditions now ( Kp = 1, K = 2, Dst = 45 nT). Quiet conditions are expected next 2 days. However enhanced solar wind conditions are again possible starting from 11-04-16 due to CME detected yesterday at the West limb of the Sun.
