Belgium now asserts that the unnamed Active Region, responsible for the M1.3 class solar flare, has disappeared from view and is on the other side of the sun facing away from us, so it may return in 14 days.

COMMENT: The unnumbered region that developed yesterday to the south of
NOAA 2664 produced an M1.3 flare peaking at 16:15 UT on July 3. This region
is now behind the limb but still producing C-class flares, and can continue
to do so in the next 24 h.

AR2663 has not yet materialized from its 14 day trek on the far side of the sun.
Something is softly flaring on the far side of the sun next to the left limb, but it is in the southern hemisphere, while AR2663 was to the North.

Lord Jesus Christ, have mercy on me a sinner.

Very important information regarding this Solar Minimum. This could be the deepest one in two centuries such as during the early 1800s, but scientists do not know how long it will last. In the late 1600s to early 1700s when people could ice skate on the River Thames in London. Remember George Washington and his soldiers in the 1770s, and how many suffered frostbite. This was during the time when the earth was just emerging from a very deep solar minimum.

SUNSPOTS ARE VANISHING: Today, July 5th, the sun is blank--no sunspots. White light images from NASA's Solar Dynamics Observatory show no dark cores anywhere on the solar disk:

This marks the 44th day in 2017 without sunspots. So many blank suns is a clear sign that Solar Minimum is approaching. The last time the solar cycle shifted in this way, 10 years ago, the sun plunged into the deepest Solar Minimum in a century. Between 2008 and 2009, sunspots were absent almost all the time; cosmic rays from deep space penetrated the solar system in record numbers; and Earth's upper atmosphere collapsed. We are on the verge of this happening again.

Yesterday, July 4th, at a meeting in the UK, researchers led by Prof. Yvonne Elsworth at the University of Birmingham reported that acoustic waves inside the sun shifted frequencies during the previous Solar Minimum (2008-2009), and those frequency shifts have persisted to the present day. "This lends weight to speculation that a fundamental change in the nature of the [sun's magnetic] dynamo may be in progress," they stated in a paper recently published in the Monthly Notices of the Royal Astronomical Society. These findings suggest that another deep Solar Minimum could be in the offing. Stay tuned for more blank suns.

Emphasis is mine. My dad, who was an astrophysicist, told me repeatedly that our sun is an unstable star. No wonder Hawkings is advising people to leave this world. For those who wait, Heaven awaits us if we are good.

UPDATE:

A newly unnamed active region has just appeared today, July 5, 2017 2015 UT on the left limb of the sun in the Southern Hemisphere. It appears to be increasing when viewed at 2030 UT (1:30 PM PDT). Time will tell. Will it continue to increase in size and in magnitude or will it suddenly decline?

As this jpg image from NASA is dynamic, I cannot link it because it takes up band width. Please click the above image to view this new active region, but realize that new images of the sun are posted about every 15 minutes.

Here is another image from NASA showing this active region flaring.

It is confirmed by NOAA. The new Southern Active Region, an alpha, has been given the number: AR266.

According to http://www.spaceweather,

NEW SUNSPOT: Breaking a string of two spotless days, new sunspot AR2665 is emerging over the sun's eastern limb. It's a big sunspot, with a primary dark core twice as wide as Earth. The magnetic canopy of AR2665 is crackling with minor B-class solar flares, but so far nothing stronger. This is probably a mostly-quiet sunspot typical of the decaying solar cycle.

However, this new Active Region is in the Southern Hemisphere, and as Solar Cycle 25 progresses or regresses depending on how deep this solar minimum is, there will be more sunspots showing up in the Southern Hemisphere.

Lord Jesus Christ, have mercy on me a sinner.

Here is a recent video showing the rapid development of Active Region AR2665.
