The explosion almost certainly produced a CME, but it won't be Earth-directed because of the blast site's farside location. Solar flare alerts: SMS Text. A SYMPHONY OF MAGNETIC WAVES: On Nov. 8th, for only a few hours, Earth's magnetic field became very quiet. In the silence, a symphony ensued. Citizen scientist Rob Stammes recorded the performance using his magnetometer in Lofoten, Norway. "At first, the line on the digital chart recorder seemed flat," he says, "but when I zoomed in I saw an almost musical superposition of sine waves." 
"This is very striking," says Stammes, who has spent years observing and cataloging magnetic disturbances inside the Arctic Circle. "Note how the high-frequency Pc1 and Pc2 waves are superimposed on the slower Pc3. In musical terms, it's a form of vibrato modulation." "Pc" stands for "pulsation continuous." This is research jargon meaning, essentially, sine waves in the magnetosphere. They are present at all times, usually as a noisy cacophany of competing frequencies. Only during moments of extreme quiet can a few individual frequencies pop out and make music together. Over the years, researchers have identified 5 types of Pc waves; Stammes recorded 3 of them. Fast Pc1 and Pc2 waves are associated with protons spiralling around Earth's magnetic field. These waves scatter so-called "killer electrons" out of the Van Allen radiation belts, making space safer for satellites. Slower Pc3 waves are a gentle flutter caused by solar wind blowing down the flanks of the magnetosphere. (Imagine blowing across a piece of paper, making it flutter with your breath. Same idea.) "Magnetic storms are great," says Stammes, "but sometimes the 'quiet' can be just as interesting." Realtime Aurora Photo Gallery

DRAGON FIRE OVER THE GULF OF MEXICO: Last night, Nov. 8th, four astronauts in a SpaceX Crew Dragon capsule splashed down off the coast of Florida, returning home from a six-month mission to the ISS. "It was a show to savor for a lifetime," says astronomy professor Wayne Wooten, who photographed the re-entry from Pensacola: 
"It appeared at 9:25 PM as an orange dot rising just under Jupiter," says Wooten. "Then it arced back downward to safe landing in the Gulf of Mexico. At its brightest, the Dragon rivalled Jupiter and looked fiery bright orange in binoculars." more images: from David Kriegler of Gulf Shores, Alabama; Realtime Space Weather Photo Gallery

Every night, a network of NASA all-sky cameras scans the skies above the United States for meteoritic fireballs. Automated software maintained by NASA's Meteoroid Environment Office calculates their orbits, velocity, penetration depth in Earth's atmosphere and many other characteristics. Daily results are presented here on Spaceweather.com. On Nov 09, 2021, the network reported 48 fireballs.
(33 sporadics, 13 northern Taurids, 1 Orionid, 1 omicron Eridani)  In this diagram of the inner solar system, all of the fireball orbits intersect at a single point--Earth. The orbits are color-coded by velocity, from slow (red) to fast (blue). [Larger image] [movies] Potentially Hazardous Asteroids ( PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time. On November 9, 2021 there were 2231 potentially hazardous asteroids.

These balloons are equipped with sensors that detect secondary cosmic rays, a form of radiation from space that can penetrate all the way down to Earth's surface. Our monitoring program has been underway without interruption for 6 years, resulting in a unique dataset of in situ atmospheric measurements. Latest results: Our most recent flight on June 25, 2021, confirms a trend of decreasing cosmic radiation: 
Cosmic ray dose rates peaked in late 2019, and have been slowly declining ever since. This makes perfect sense. Solar Minimum was in late 2019. During Solar Minimum the sun's magnetic field weakens, allowing more cosmic rays into the solar system. We expect dose rate to be highest at that time. Now that Solar Minimum has passed, the sun is waking up again. Solar magnetic fields are strengthening, providing a stiffer barrier to cosmic rays trying to enter the solar system. The decline of cosmic radiation above California is a sign that new Solar Cycle 25 is gaining strength. .Who cares? Cosmic rays are a surprisingly "down to Earth" form of space weather. They can seed clouds, trigger lightning, and penetrate commercial airplanes. According to a study from the Harvard T.H. Chan school of public health, crews of aircraft have higher rates of cancer than the general population. The researchers listed cosmic rays, irregular sleep habits, and chemical contaminants as leading risk factors. Somewhat more controversial studies (#1, #2, #3, #4) llink cosmic rays with cardiac arrhythmias and sudden cardiac death. En route to the stratosphere, our sensors also pass through aviation altitudes: 
In this plot, dose rates are expessed as multiples of sea level. For instance, we see that boarding a plane that flies at 25,000 feet exposes passengers to dose rates ~10x higher than sea level. At 40,000 feet, the multiplier is closer to 50x. The higher you fly, the more radiation you will absorb. Technical notes: The radiation sensors onboard our helium balloons detect X-rays and gamma-rays in the energy range 10 keV to 20 MeV. These energies span the range of medical X-ray machines and airport security scanners. Data points in the first graph ("Stratospheric Radiation") correspond to the peak of the Regener-Pfotzer maximum, which lies about 67,000 feet above central California. When cosmic rays crash into Earth's atmosphere, they produce a spray of secondary particles that is most intense at the entrance to the stratosphere. Physicists Eric Regener and Georg Pfotzer discovered the maximum using balloons in the 1930s and it is what we are measuring today. | | The official U.S. government space weather bureau | | | The first place to look for information about sundogs, pillars, rainbows and related phenomena. | | | Researchers call it a "Hubble for the sun."
