2020 August 12 Sun - AR12769 and AR12770, and possible AR12771 and AR12772

Solar observers please note:

AR12769 is close to the NW limb, at (N27W77).

AR12770 is in the western hemisphere, at (N23W36). Bright flares are visible, so is a single sunspot.

Today, a small active region (possible AR12771)shows up near the Se limb, at about (S20E58). 3 small sunspots are visible. Magnetic reversal is present, thus this belongs to the 25th solar cycle.

Right on the SE limb, to the SE of AR12771, is another active region, located at about (S28E85). A bright faculae is visible. However, the view is too much foreshortened and it is not possible to say if sunspot is present. Magnetic reversal is also seen. This maybe designated AR12772.

sunspot count: group=2, sunspot=4, R=24
