Most of them are coming from NOAA AR 713, which will cross the Western limb today. However, the new active region NOAA AR 715 at the Eastern limb is already taking over the show. Meanwhile, a persistent Southward pointing of the interplanetary magnetic field induces mildly disturbed geomagnetic conditions (K=4).
