Sun activity: AR3272 growing, coronal hole vanishing

Earth’s geomagnetic field continues calm. And the Earth-facing side of the sun has just two sunspot regions, plus a vanishing coronal hole. AR3270 appears on the sun’s southwest limb (edge) and it is now departing. All eyes are turned to AR3272, which recently rotated into view in the sun’s southeast quadtrant. During the past day, AR3272 increased in size and in the number of spots maintaining its beta-gamma configuration. Flaring productivity also increased (detailed below). NOAA forecasters increased their analysis of chances for C flares from AR3272 to 95%, which is now moving into a geoeffective position. That is a place on the sun where any possible CMEs from this region might affect Earth and cause auroral displays.
