Bülletään

Solar flaring activity is at C-class level with a C5.5 flare as main event from NOAA AR1698, which is behind the west limb now. In the next few hours solar activity is expected to be quiet. Small C-class flares are likely with NOAA AR1692 (and AR1695) being the biggest candidate as source region. The last 12 hours the solar wind speed was between 400 and 500 km/s, now being 470 km/s. The Bz-component of the interplanetary magnetic field is fluctuating between -5 and +5 nT. Geomagnetic conditions are quiet to unsettled and are expected to increase within the next 24 to 48 hours to active to minor storm levels, due to the expected arrival of a halo CME of Sunday March 17 at 15h48 UT. From analysis of new data, the CME measured yesterday at 8h UT is related to the NOAA AR 1698 and will probably not arrive at Earth.
