Bülletään

Solar activity is on the rise with M class flares likely from NOAA ARs 1731 and 1730. The latter showed quick evolution from yesterday and is it now a beta-gamma-delta region. C flares are expected from NOAA ARs 1732, 1733 and to a lesser extent AR 1734. Warning conditions are raised for protons, due to the position of AR 1730 on the disk and the risk of M class flare. The strongest flare of the last 24 hours was a C5.9 at 2032 UT peak time, in NOAA AR 1730. No CME is associated with this event. We expect mostly quiet conditions for the geomagnetic activity during the next 48 hours. Current conditions are quiet. ACE observations show a slight increase of the solar wind speed and weak excursions of the interplanetary magnetic field.
