The Sun is not even safe from the NSA.

'hedgerow prominence"
A gigantic filament of plasma is dancing along the northwestern edge of the sun, rising more than 150,000 km above the solar surface. How large is that? It's fully 1/10th of the sun's diameter and almost a dozen times taller than our entire planet. Click to view a 2-day movie from NASA's Solar Dynamic Observatory.
This is called a "hedgerow prominence." Hot glowing plasma inside the structure is held aloft by unstable magnetic fields. If the magnetic support collapses, plasma can fall back to the solar surface, exploding in a Hyder flare--a type of solar flare that can occur with no underlying sunspot.
NASA and Japanese space telescopes have taken high resolution images of similar prominences and seen some amazing things such as (1) tadpole-shaped plumes that float up from the base of the prominence; (2) narrow streams of plasma that descend from the top like waterfalls; and (3) swirls and vortices that resemble van Gogh's Starry Night.
NOAA forecasters said there was a 75% chance of a CME impact on March 23th. That means there was a 25% chance of no impact. Indeed, we're still waiting for the CME to arrive. The tardy arrival could mean that either (1) the CME missed or (2) it is moving more slowly than expected. Either way, the chance of storms is waning as March 24th approaches.
Let us hope Active sunspot AR2736, which hurled a CME toward Earth on March 20th, was nonviolent.

Makes me wonder if they would tell us.

Of course not.

Looks like the CME just hit me.
Has me grunting ... errgggg

COSMIC RAY BALLOON: When CMEs are coming, there's only one thing to do: Launch a cosmic ray balloon. Spaceweather.com and the students of Earth to Sky Calculus launched this one on May 13th.
The balloon carried an array of X-ray/gamma-ray sensors to the stratosphere more than 100,000 feet above Earth's surface. The students have been launching these balloons almost once a week for the past 4 years. They find that cosmic rays are increasing--a trend that might temporarily reverse this week.
CMEs sweep aside cosmic rays, causing atmospheric radiation levels to drop. The phenomenon is called a "Forbush Decrease," named after physicist Scott E. Forbush who first described it. The May 13th launch established a baseline by measuring levels before the CMEs arrived. During- and after-CME launches will take place in the days ahead. Stay tuned for results.
Of primary cosmic rays, which originate outside of Earth's atmosphere, about 99% are the nuclei of well-known atoms (stripped of their electron shells), and about 1% are solitary electrons (that is, one type of beta particle).
Of the nuclei, about 90% are simple protons (i.e., hydrogen nuclei); 9% are alpha particles, identical to helium nuclei; and 1% are the nuclei of heavier elements, called HZE ions.
A very small fraction are stable particles of antimatter, such as positrons or antiprotons.
Ready the anti ballons.
These particles may just what would be gun shot residue but from alien ray guns.
