Solar activity has been active during the past 24 hours, featuring four C flares and one M1.3 flare. The M flare was produced by AR 11745 (which also released the majority of the C flares) and had its peak around 12:56 UT on May 10. More C flares and even M flares are likely within the next 48 hours, especially from NOAA AR 11745. In the last 24 hours, the IMF has been steady around 4 nT, while solar wind speeds have decreased from about 440 and to 390 km/s. On May 12, a weak coronal hole high speed stream may cause solar wind speeds to increase again up to 500 km/s. Geomagnetic activity has been at quiet levels (K Dourbes between 0 and 3; NOAA Kp between 0 and 2) during the past 24 hours. Quiet geomagnetic conditions (K Dourbes < 4) are expected for May 11 to 13, with a chance for active levels (K Dourbes = 4) on May 12, due to a weak coronal hole high speed stream.
Today's estimated international sunspot number (ISN): 087, based on 06 stations.
