You can, too! | | | WAITING FOR THE CME: A coronal mass ejection (CME) expected to sideswipe Earth's magnetic field on May 28th has still not arrived. No problem; a geomagnetic storm happened anyway. Unrelated to the CME, a solar wind stream sparked 12 hours of G1-class storming on May 27-28. Meanwhile, the CME might still be en route, moving more slowly than expected. Stay tuned. Aurora alerts: SMS Text AURORAS IN THE USA: Marybeth Kiczenski has been waiting years to take this picture. "Finally, last night I captured Northern lights over the Mackinac Bridge in Michigan!" she says. "I decided to break out the telephoto lens for a close-up shot," she says. "Despite making the aurora a bit diffused due to the light pollution, it was neat to see!" This display was caused by a co-rotating interaction region (CIR), which hit Earth on May 27th. CIRs are transition zones between slow- and fast-moving streams of solar wind; they contain shock waves that often do a good job sparking auroras. This particular CIR caused a G1-class storm on May 27th. A fast stream of solar wnd arrivng right behind it kept the storm going into the early hours of May 28th. more images: from Brian Larmay of Pembine Wisconsin; from Rodrigo Roesch of Kewaunee, Wisconsin; from Tim Wieland of Charlevoix, Michigan; from Shayne Smith of Manistique, Michigan Realtime Aurora Photo Gallery Free: Spaceweather.com Newsletter LUNAR OCCULTATION OF VENUS: For almost 5 hours yesterday, the planet Venus disappeared. It was hiding behind the Moon. Quentin Gineys photographed the lunar occultation from Réunion Island in the Indian Ocean: "To observe the occultation, I used an 11-inch Celestron telescope," says Gineys. "The phenomenon was very low, only 10 degrees above the horizon. I had to prepare my shooting location well, between roofs, a relay antenna and many palm trees." The occultation was not visible everywhere. To see it, you had to be inside a narrow path stretching from southeast Asia to the Indian Ocean. Elsewhere, the Moon-Venus encounter was a beautiful near miss. more images: from Shahrin Ahmad of Kuala Lumpur, Malaysia; from Hari Kumar of Trivandrum, India; from Andreas Walker of Rorschacherberg, Switzerland; from Gadi Eidelheit of Givat Shmuel, Israel; from Michal Lachký of Chynorany, Slovakia Realtime Space Weather Photo Gallery Free: Spaceweather.com Newsletter CAPT.

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."
