Bulletin

Over the past 24 hours solar activity has been moderate. The largest flare was a C3.2 class flare. Active Region (AR) 2542 (Macintosh class:Cai; Mag. type:Beta) produced the largest flare, the C3.2 class flare, peaking at 16:03 UT yesterday. ARs 2544 (Dai; Beta-gamma) and 2545 (Cao; Beta) also produced a couple of B and C class flares. AR 2544 has exhibited significant flux emergence and cancellation in HMI observations, which may lead to further flares. A partial halo CME with angular width of 158 degrees and a speed 538 km/s (as measured by the CACTUS automated CME detection algorithm) was observed at 15:24 UT yesterday. The CME was produced from a filament eruption that occurred in the Western hemisphere (N10W62), near the solar limb. The eruption was associated with the above- mentioned C3.2 flare. The CME is largely orientated to the West, however, an Earth directed component may be expected to interact with the Earth system on 18-May-2016 at 16:30 UT +/- 12 hours. Solar protons have remained at background levels over the past 24 hours, with a small peak at 21:00 UT yesterday evening, which may have been related to the above mentioned CME. Solar activity is expected to remain moderate over the next 24 hours with a high probability of C-class flares and a medium probability of M-class flares. The solar wind speed has increased from around 400 to 550 km/s over the past 24 hours. The total magnetic field strength has remained around 9 nT. The Bz component fluctuated between -9 and +9 nT. The fluctuating magnetic field may lead to increased geo-activity over the coming day. Geomagnetic conditions ranged between Kp index 2-4 (NOAA) and local K index 1-4 (Dourbes) over the past 24 hours. A positive polar coronal hole is currently positioned in the Western hemisphere of the Sun and the resulting high-speed stream (HSS) may enhance solar wind speeds later today and as a consequence may increase geo-activity levels. The CME produced at 15:24 UT on 15-May-2016 may also increase geo-activity at the Earth around 16:30 UT (+/- 12 hours) on 18-May-2016.

Today's estimated international sunspot number (ISN): 064, based on 19 stations.
