Bülletään

During last 24 hours several B-class and one C-class flare were reported. All the flaring activity originated from the Catania sunspot group 73 (NOAA AR 2007) which is presently situated rather close to the west solar limb. The strongest C1.9 flare peaked at about 11:07 UT today. The coronagraph observations show that the CMEs associated with reported flares were mostly narrow and rather slow and will therefore not arrive to the Earth. During last 24 hours solar protons remained at background level.

The Earth is presently inside the slow solar wind with the speed of about 350 km/s, and the interplanetary magnetic field magnitude is 4 nT. We might expect increase of the solar wind speed in the coming hours, associated with the coronal hole which reached central meridian in the morning of February 26. The geomagnetic conditions were quiet during last 24 hours and we expect quiet to unsettled geomagnetic conditions in the coming hours.
