active sun

AR4432 has not stop growing, now it has two big dark cores, the main one is about 3 Earths wide and observable with protected eye alone. Plus, is presents now an unstable delta gamma configuration which could emit M-class flares before going beyond the western limb. The action came from AR4436 (former 4419) which produced a strong M 5.8-class flare today morning, it seems more is to come from this spot
