All three Betas have increased in size and in strength. AR2714 is nearest the Western Limb of the sun and will be departing in the next few days. It appears to be the smallest of the three, but it is actively B flaring.
The Royal Observatory at Belgium has estimated the sunspot number (EISN) for June 20, 2018 to be 57, while the average EISN for the month of June is approximately 14. No doubt, this average mean will increase as the three Betas travel across the sun.
The GOES X-ray flux shows that the output of the sun is now in the low B-range. We could have C flaring. Two sunspots have been actively flaring: AR2714 and the rapidly developing AR2715. If they unleash CMEs, these could be geo-centered (AR2715) or geo-directed (AR2714).

Here is one image of the sun which shows how large these Betas are:

Below is another image of the sun showing the three Betas along with a developing region at the Eastern Limb.
Will this area (possibly the return of AR2712) develop further or will it remain a plage?
