There are currently nine numbered sunspot groups on the solar disc. The solar activity remains low with only few C-class flares reported during last 24 hours. Weak, long duration flare (not reported) which peaked at about 11:05 UT on May 12, originated from the Catania sunspot group 47 (NOAA AR 2060). The flare was associated with coronal dimming, an EIT wave and CME. The CME had angular width of 130 degrees and projected speed of about 600 km/s. The bulk of the CME mass was oriented southward of the Sun- Earth line, and this CME will not arrive at the Earth. We expect C-class flares and possibly also an isolated M-class flare. Catania sunspot groups 42 and 43 (NOAA ARs 2055 and 2056, respectively) are currently situated in the western solar hemisphere, a major eruption in one of them may lead to a proton event, so we issue warning condition for a proton event. The solar wind speed is about 350 km/s. The interplanetary magnetic field is stable with the magnitude between 1 and 2 nT. The fast flow associated with the small equatorial corona hole which reached the central meridian yesterday might arrive at the Earth on May 15, producing at most unsettled geomagnetic conditions. The fast flow from the small and narrow equatorial coronal hole which reached the central meridian on May 11 might arrive in the morning of May 14. The geomagnetic conditions are at the moment quiet and expected to remain so in the following hours.
