Details:
Sesion with cloudy weather, hence images of low quality, but it was worth since various events happened in Active Regions. 4136 in N hemisphere has now delta field and has an active companion numbered 4139, here catched erupting a small filament (partly enlightened with a little flare), at least temporarily. Possibly even more interesting is AR4140 in South hemisphere, rising today: It produces frequent eruptions (with flares), as we saw also in recent days when it was still behind limb. I also catched a flare in 4134. Sun X-rays flux level was C1 during all session. Lunt60 H-alpha scope, Neptune-M camera. Seeing 1/5, transparency 2/5.
