As of 4:05 PM PDT, here is the latest EISN data from Belgium's Royal Observatory associated international astronomers.

Average mean EISN for May is approximately 14.

Update from NOAA: AR2712 has been teasing us, appearing to decay only to come to life again ... Not only has AR2712 increased in area, but also it is now a Beta-Gamma, and as it travels across the sun, and approaches the Western Limb, it may unleash a geo-directed solar flare. Beware. Our shield is down during this solar minimum.

In addition to the threat of AR2712, we are having increased solar winds which are predicted to hit the earth on June 1.+

Ah! Time to compare and see the EISN for May 2018.

Below is the EISN Plot taken at the end of the month in May 2018 with an estimated average mean EISN of ~14.

And immediately above is the EISN Plot (edited by Belgium's Royal Observatory) for May and June 2018, with an average mean EISN that is above 14. Note that next month could see a decline in the EISN as we approach a deep solar minimum.
Again, note that all of these recent active areas have been from the Northern Hemisphere of the sun, but as we transit from a solar minimum to a new solar maximum, most of the active regions will come from the Southern Hemisphere of the sun, so we still have a long way to go before the next peak of solar activity.

New update from http://www.spaceweather.com

Sunspot AR2712 has developed a beta-gamma magnetic field that harbors energy for M-class solar flares.


Notice the image below showing the flaring AR2712. Something approaches from the Northeastern Limb of the sun. Next, look at the equatorial coronal hole from which solar winds have reached the Earth. This coronal hole looks like a roadrunner.

Below is the GOES X-ray three day plot (updated every five minutes, so disregard the label at the top). AR2712 is becoming more active now that it is reaching the geo-directive Western Limb of the sun. Therefore, we could be due for a rare surprise with an M or X flare or two, which happened in September 2017. Note also that earth's protective shield is down during this time of a solar minimum.

Here is the latest NOAA report showing that AR2712 is still growing in size (Area was 50, now is 60) and strength (Mag. was 11, but is now 12). The new active region is now in view, but NOAA did not mention it. Will it fade away like many new active regions during this solar minimum, or will it increase in size and magnetism as is AR2712?

Just in from NOAA: AR2712 has now declined in area from 50 to 30, and in magnetism from a Beta-Gamma to a Beta. In a day or so, it will depart this side of the sun. In doing so, will it return in 12 to 14 days? That is unlikely during a solar minimum.

AR1712 has come back to life.

Look at this GOES X-ray flux showing an impulsive B7.9 flare

Then look at this picture of the sun with AR2712 actively flaring. Could it have unleashed a CME?
