Bulletin

Solar activity once more was very low. Beta region NOAA AR 2552 is the only sunspot region on the frontside of the Sun and produced no C flares. Solar activity is expected to remain very low (no C flaring) for the next 24 hours. CACTUS detected a northward CME in LASCO C2 data at 01:48 UT on June 9, which is most probably associated with a backside event. During the past 24 hours, ACE solar wind speed decreased from about 440 to about 350 km/s. Meanwhile, the magnitude of the Interplanetary Magnetic Field (IMF) varied between 1 and 7 nT. During the past 24 hours, geomagnetic conditions have been quiet to unsettled (K Dourbes between 0 and 3; NOAA Kp between 0 and 2). Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected on June 9 and 10, with a chance for active geomagnetic levels (K Dourbes = 4) on June 10 due to an expected sector boundary crossing. Due to the expected arrival of a positive coronal hole high speed stream, active geomagnetic conditions are possible on June 11, with a chance for minor storm intervals (K Dourbes = 5).

Today's estimated international sunspot number (ISN): 019, based on 23 stations.
