Bülletään

Since our last bulletin, three C-class flares were produced. They all originated from Catania sunspot group 8 (NOAA AR 1926). The GOES X-ray flux background was at B-class level. A new region emerged near S03E30. Eruptive flaring activity is expected for the next 48 hours with a slight chance for M-class flares. No Earth bounded CMEs were observed. Solar wind observations from ACE showed an increase of the solar wind speed at 17h UT of April 7 from 360 to 480 km/s and then a decline to 400 km/s. The magnitude of the interplanetary magnetic field varied between 1 and 11 nT, with a Bz component fluctuating between -10 and 6 nT. The periods with a negative Bz resulted in unsettled to active magnetic conditions (both local K at Dourbes and NOAA planetary Kp). So far, there were no clear signatures of arrival of a shock related to the CME of April 4, but it is still possible in the next few hours. Unsettled conditions are expected for the next 48 hours.
