It comes after the eruption of the ‘Dragon’ star or EK Draconis, a G1.5V yellow dwarf located 110.71 light-years away from the Earth.

Scientists have highlighted that solar flares lead to mass ejections that directly affect the Earth’s environment.

”This kind of big mass ejection could, theoretically, also occur on our sun. This observation may help us to better understand how similar events may have affected Earth and even Mars over billions of years,” said co-author Yuta Notsu from Laboratory for Atmospheric and Space Physics (LASP).

The study published in the Nature journal shows that M-type red dwarf stars are not as stable as previously thought. However, the sun appears to be far less active than similar stars in terms of brightness variations caused by sunspots and other phenomena.

Researchers said on Thursday that an examination of 369 stars similar to the sun in surface temperatures, size, and rotation period, it takes the sun about 24-1/2 days to rotate once on its axis, showed that they displayed on average five times more brightness variability than the sun.

“This variability is caused by dark spots on the surface of the star rotating in and out of view,” said astronomer Timo Reinhold of the Max Planck Institute for Solar System Research in Germany.

The sun, essentially a hot ball of hydrogen and helium, is an average-sized star that formed more than 4.5 billion years ago and is roughly halfway through its lifespan. Its diameter is about 864,000 miles (1.4 million km). Its surface temperature is about 10,000 degrees Fahrenheit (5,500 degrees Celsius).

“Temperature and rotation period are thought to be the major ingredients for the dynamo inside the star, which generates its magnetic field, and eventually the number and size of the spots causing the brightness to vary. Finding such stars with very similar parameters as our sun but being five times more variable was surprising,” Reinhold said.

Elevated magnetic activity associated with sunspots can lead to solar flares, coronal mass ejections, large expulsions of plasma and magnetic field from the outermost part of the sun’s atmosphere, and other electromagnetic phenomena that can affect Earth, for example disrupting satellites and communications and endangering astronauts.

“A much more active sun might have also affected Earth on geological time scales, paleo-climatology. A ‘too active’ star would definitively change the conditions for life on the planet, so living with a quite boring star is not the worst option,” Reinhold said.

The researchers compared data on similar stars to historical records of the sun’s activity.

These records included about 400 years of observational data on sunspots and about 9,000 years of data based on chemical element variants in tree rings and ice cores caused by solar activity. They indicated the sun has not been much more active than it is now.

The findings, Reinhold said, do not rule out that the sun may be in a quiet phase and may become more variable in the future.

They used the word “dire”. Hmm.

Above we see the Dragon Nebula which has erupted today, Christ Michael slaying the dragon, and the Ouroboros, the snake eating its tail as the symbol for the number 8, and the infinity symbol or the lemniscate. This speaks to the Mayan tribe Yellow Sun~Blue Storm mediated by Pluto. Note the synchronicity that in the Tzolkin, the RED DRAGON tribe directly follows the Yellow Sun Tribe. Red Dragon~White Mirror is mediated by Neptune.

“And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon turned red. And the stars of heaven fell unto the earth (E.T. ships here to help us), even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind. And the heaven departed as a scroll when it is rolled together; and every mountain and island were moved out of their places (tectonic plates moved)

Revelation 6:12-14

“And after these things I saw four angels standing on the four corners of the earth, holding the four winds of the earth, that the wind should not blow on the earth, nor on the sea, nor on any tree. And I saw another angel ascending from the east, having the seal of the living God; and he cried with a loud voice to the four angels, to whom it was given to hurt the earth and the sea, Saying, Hurt not the earth, neither the sea, nor the trees, till we have sealed the servants of our God in their foreheads (the pineal gland, the 3rd eye!) Those that were sealed was 144,000.”
