Bulletin

Six sunspot regions are visible at the front side of the solar disk. The background level of the X-ray flux measured by GOES is at B-class level. No solar flares were observed during the past 24 hours. LASCO/C2 observed at 8:36 UT a CME, which is associated with a backsided event. No Earth-directed CMEs were detected. C-class flares are expected for the next 48 hours, with NOAA ARs 2077 and 2079 as strongest source candidates. We are currently experiencing slow solar wind conditions, with a speed between 260 and 300 km/s. The magnitude of the interplanetary magnetic field is stable near 5 nT, with a fluctuating Bz component between -5 and +5 nT. The geomagnetic conditions were quiet. A small coronal hole that passed the central meridian on 29 May can still influence the geomagnetic field within the next 24 hours. Geomagnetic conditions are expected to remain quiet, though locally a brief active episode is possible.

Today's estimated international sunspot number (ISN): 041, based on 19 stations.
