Magnetometers in Boulder, CO, registered a sudden impulse of 30 nanoTeslas. This may be a previously unrecognized CME embedded in the solar wind. Minor G1-class geomagnetic storms are possible in the hours ahead as Earth's magnetic field reverberates from the impact. Solar flare alerts: SMS Text. A SUNSPOT MADE IN CHINA: For a split second on Sept. 12th, the sunspot number increased by 1. The extra sunspot was made in China. "It was the Tiangong space station," explains Juan Carlos Casado, who watched the winged silhouette cross the sun from his backyard in Figueres, Spain: 
China has been building Tiangong since its first core module was launched in April 2021. The growing station has more than doubled in size in the past year. With solar arrays, a robotic arm, multiple modules, and two spacecraft (Tianzhou 4 and Shenzhou 14) waiting at docking ports, Tiangong is starting to look a lot like the ISS. The ISS is still much larger, but China is catching up. When it is completed in December 2023, Tiangong with be a Mir-class facility massing nearly 70 tons with living space for as many as 7 astronauts and even a Hubble-class telescope to view the cosmos. Meanwhile, it's an awesome sunspot. "Tiangong is so large I had no trouble resolving it using a small telescope (15 cm aperture)," says Casado. "It was in front of the sun for only 0.6 seconds. My conventional mirrorless camera shooting in burst mode (10 images per second) caught it six times." Realtime Space Weather Photo Gallery
Free: Spaceweather.com Newsletter THE SUNBURST X-PENDANT: It's the color of a sunburst: The Citrine X-Pendant. The students of Earth to Sky Calculus launched this one to the stratosphere onboard an cosmic ray research balloon. At the apex of the flight it floated 120,892 feet above Earth's surface--a record high for our 10-year ballooning program:
You can have it for $199.95. The citrine gemstone is framed in a 18K gold-plated swirl with a matching 16-inch chain. The students are selling these pendants to support their cosmic ray ballooning program. Each one comes with a greeting card showing the necklace in flight and telling the story of its journey to the edge of space. Far Out Gifts: Earth to Sky Store

Free: Spaceweather.com Newsletter 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 Sep 14, 2022, the network reported 26 fireballs.
(24 sporadics, 2 Sept. epsilon Perseids)  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 September 14, 2022 there were 2293 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 (July 2022): Atmospheric radiation is decreasing in 2022. Our latest measurements in July 2022 registered a 6-year low: 
What's going on? Ironically, the radiation drop is caused by increasing solar activity. Solar Cycle 25 has roared to life faster than forecasters expected. The sun's strengthening and increasingly tangled magnetic field repels cosmic rays from deep space. In addition, solar coronal mass ejections (CMEs) sweep aside cosmic rays, causing sharp reductions called "Forbush Decreases." The two effects blend together to bring daily radiation levels down. .Who cares? Cosmic rays are a surprisingly "down to Earth" form of space weather. They can alter the chemistry of the atmosphere, 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. A number of controversial studies (#1, #2, #3, #4) go even further, linking 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 graph labeled "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."
