"GEOMAGNETIC STORM WATCH (G2): Geomagnetic storms are possible on Aug. 1st when a #CME is expected to hit Earth's magnetic field. Minor G1-class storms are likely with a chance of escalating to category G2. The CME was hurled almost directly toward Earth by the eruption of a magnetic filament in the sun's northern hemisphere on July 28th. Aurora alerts: SMS Text

"#PROTONS ARE *STILL* HITTING EARTH'S ATMOSPHERE: For the second day in a row, energetic protons from the sun are raining down on Earth's atmosphere. This is called a "radiation storm" (S1-class), and it was caused by a magnificent eruption on July 28th.

"The blast site was hidden from view just behind the sun's northwestern limb. Earth-orbiting satellites registered an M4-class solar flare, but the underlying explosion was stronger. It was probably an X-flare partially eclipsed by the edge of the sun.

"How can a sunspot not facing Earth send so many protons in our direction? The answer is 'the #ParkerSpiral.' Take a look. As the sun spins, its magnetic field spirals like water flowing from a twirling lawn sprinkler. Lines of magnetic force emerging from behind the sun's northwestern limb (where the explosion happened) spiral back and make a direct connection to Earth. It's a superhighway for energetic protons.

"This #RadiationStorm looks like it will continue at S1 levels for at least one more day. Its main effect is a polar cap absorption event (PCA) inside the Arctic Circle. Right now, #shortwave radios around the north pole aren't working very well."

A new way to study #quarks, one of the building blocks of the #protons and #neutrons that make up #atomic #nuclei, is proposed. This has never been done before and doing so would help answer many fundamental questions in physics.

There's a lot more to Protons than you might think!

#Gluons are always popping in and out of existence like blinking fireflies. But when #nuclei or #protons are accelerated to high energies, the gluons inside appear to multiply. That's because time operates in weird ways near the speed of light.

Interesting, but I can't say I really understand it. #physics #protons #quarks
