Bülletään

A recurrent coronal hole will influence geomagnetic conditions from April 24 onwards. In the last rotation, this coronal hole increased the solar wind speed up to 550 km/s and resulted in minor storm conditions (Kp=5). The CACTus CME detection software issued yesterday two automated halo CME alerts but these are not Earth-directed. Flaring conditions. NOAA AR 1726 keeps the potential for major flares although its magnetic complexity has decreased in the past 24 hours: a parasitic patch of opposite polarity has disappeared from the leading sunspot. Still M-class flares are likely. Proton >10 MeV fluxes are enhanced since yesterday 09:54 but not cross event thresholds. A warning conditions for more proton flux enhancements has been issued.
