Well a BIGGIE sunspot will be facing earth within days, and just may very well trigger a BIGGIE earthquake as well. So everyone just STAY SAFE

Astrophysicists aren't sure exactly what these eruptions are, but they all unanimously agree that they are caused by Donald Trump.

That is a neat picture.

AN EXPLOSION OF PINK AURORAS: If you spend 10 years inside the Arctic Circle, you're going to see a lot of auroras. "I have been guiding aurora tours full time for the past decade, leading more than 1000 tours," says Markus Varik of Tromsø, Norway. "I thought I had seen it all." Think again:
"We headed out early last night (Nov. 2nd) to chase the lights--and what a surprise!" he says. "These were the most intense pink auroras I have ever seen. The pink color was bright and obvious to the naked eye. My entire group was stunned."
Pink auroras are a sign of nitrogen. Most auroras are green--the color of oxygen atoms being struck by energetic particles 100 km to 300 km above Earth's surface. Pink appears when energetic particles from space descend lower than usual, striking nitrogen molecules at the 100 km level and below.
What happened? Just before Varik went out aurora hunting, a crack formed in Earth's magnetic field. Energetic particles rushed through the gap, penetrating deeply enough for pink

Huge Piece Of Sun Breaks Off, Scientists Stunned
Scientists are trying to understand the impact this huge prominence will have on Earth.
The Sun has always fascinated astronomers. And now, a new development has baffled scientists. A huge part of the Sun broke off of its surface and created a tornado-like swirl around its North Pole. Though scientists are trying to analyse how this occurred, the video of the development has stunned the space community. The remarkable phenomenon was caught by NASA's James Webb telescope and shared on Twitter by Dr Tamitha Skov, a space weather forecaster, last week. The Sun keeps emitting solar flares (called prominence) that sometimes affect communications on Earth, hence scientists are more concerned about the latest development.
"Talk about Polar Vortex! Material from a northern prominence just broke away from the main filament & is now circulating in a massive polar vortex around the north pole of our Star. Implications for understanding the Sun's atmospheric dynamics above 55 degrees here cannot be overstated!" Dr Skov said in a tweet last week.

According to NASA, the prominence is a large bright feature extending outward from the Sun's surface. There have been several such instances in the past but this one has stumped the scientific community.
"More observations of the #SolarPolarVortex reveal it took roughly 8 hours for material to circumnavigate the pole at approximately 60 degree latitude. This means an upper bound in the estimation of horizontal wind speed in this event is 96 kilometers per second or 60 miles a second!" Dr Skov said in a subsequent tweet.
Solar physicist Scott McIntosh of the US National Centre for Atmospheric Research, who has been observing the Sun for decades, told Space.com that he had never seen a "vortex" like the one that occurred when a piece of the prominence broke away and was whipped into the solar atmosphere.

Thought I'd post this here given he coined the phrase.
