The walls of the canyon are at least 20,000 km high and 10 times as long. Fragments of the magnetic filament may soon emerge from the blast site in the form of an Earth-directed CME. Stay tuned and, meanwhile, watch the movie. Solar flare alerts: SMS Text LONG DURATION SOLAR FLARE AND CME: Yesterday, April 2nd, departing sunspot AR2975 exploded, producing a long-duration M4-class solar flare. Although the sunspot was not directly facing Earth, it might have hurled some debris in our direction: 
This SOHO coronagraph movie shows an asymmetric full-halo CME emerging from the blast site. The bulk of the CME will miss, but perhaps not all. A fraction of the storm cloud appears to be heading for Earth and could strike our planet's magnetic field on April 5th or 6th. A glancing blow could spark a minor G1-class geomagnetic storm. See all the snow at the beginning of the coronagraph movie? That is a storm of energetic protons striking SOHO's digital camera. The protons were accelerated toward Earth by shockwaves at the leading edge of the CME. Solar flare alerts: SMS Text Realtime Space Weather Photo Gallery

On April 1, 2022, he joined 270 aurora chasers on a flight toward the South Pole--and this is what they saw: 
A Cannibal CME had hit Earth's magnetic field just hours earlier, sparking a G1-class geomagnetic storm. In the northern hemisphere, auroras appeared as far south as Colorado and Nebraska. They did not compare, however, to the colorful light show Griffin witnessed. "The enthusiasts on board were treated to a wonderful display of aurora australis," says Griffin. "To see the lights, we chartered a Boeing 767 out of Christchurch and spent 10 hours in the air. For a while we were south of latitude 60 degrees--deep inside the southern auroral zone."

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 Apr 02, 2022, the network reported 8 fireballs.
(8 sporadics)  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 April 3, 2022 there were 2272 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 7 years, resulting in a unique dataset of in situ atmospheric measurements. Latest results (Nov. 2021): Our balloons have just measured a sudden drop in atmospheric radiation. It happened during the strong geomagnetic storms of Nov. 3-4, 2021. Here are the data: 
This is called a "Forbush decrease," named after American physicist Scott Forbush who studied cosmic rays in the early 20th century. It happens when a CME from the sun sweeps past Earth and literally pushes cosmic rays away from our planet. Radiation from deep space that would normally pepper Earth's upper atmosphere is briefly wiped out. We have measured Forbush decreases before. For example, here's one from Sept. 2014. The Forbush Decrease of Nov. 3-4, 2021, was the deepest in the history of our 7-year atmospheric monitoring program. Radiation levels in the stratosphere over California dropped nearly 20%, more than doubling the previous record from our dataset. En route to the stratosphere, our sensors also pass through aviation altitudes, so we can sample radiation where planes fly. This plot shows how the Forbush decrease was restricted to the stratosphere; it did not affect lower levels of the atmosphere: 
The dose rates shown above are expressed 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. .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) link cosmic rays with cardiac arrhythmias and sudden cardiac death. .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."
