NASA's Parker Solar Probe spotted 'stealth' outburst on the sun

In November 2018, as seen from Earth and certain spacecraft, the sun seemed to be calm. But it wasn't: The sun was experiencing what scientists call a "stealth" coronal mass ejection. And conveniently, NASA's Parker Solar Probe was completing its first close pass behind the sun, putting its instruments in a perfect position to see what was happening on Nov. 11 and 12 during this usually cryptic event.

"If you've ever seen a coronal mass ejection image, you normally see a lot of activity in these images," Kelly Korreck, a solar physicist at the Smithsonian Astrophysical Observatory, said during a presentation last month at the 235th meeting of the American Astronomical Society in Honolulu. "You would see a large blowout, you would probably see one of these exploding. But as you saw in this video, there wasn't much there."

Even in some of the Parker Solar Probe data, it wasn't obvious at first what was happening during the incident, Korreck said. "When we looked at this initially, just the thermal data, we didn't necessarily think that there was a coronal mass ejection there," she said.

But other observations targeting energetic particles did include the fingerprint of a shock, a phenomenon that usually accompanies a coronal mass ejection. Scientists could also confirm the probe was flying through a coronal mass ejection based on data its instruments were gathering about the magnetic field.

There is always 50% of the suns surface we don’t see.

Earlier this year, US National Oceanic and Atmospheric Administration and the British Geological Survey (BGS) were forced to update the World Magnetic Model a year ahead of schedule due to the speed with which the magnetic north pole is shifting out of the Canadian Arctic and toward Russia’s Siberia.

A stealth outburst.

Is that like when Hillary throws a fit in private and we only hear about busted champaign bottles second hand?
