The Globalstar was not big enough to fill the Falcon 9 rocket. Something else must be inside. Marco Langbroek of Leiden, the Netherlands, just photographed the secret contents, a train of four new classified satellites: "These objects (USA 328 - 331) were covertly launched with Globalstar FM15 on June 19, 2022," says Langbroek. "The second object in the 'train', USA 329, is slowly varying in brightness, which might indicate it is tumbling. It varies between about magnitude +5 and +10 with a period of around half a minute. The other payloads are steady in brightness, at about magnitude +7/+8." A much brighter 5th object following the train is a piece of debris from the Falcon 9 rocket that carried the satellites to space. "The Falcon 9 debris piece is about mag +4.5 to +5," says Langbroek.

Apollo Lasky of Naperville, Illinois, photographed the twister on June 21st, the summer solstice, using a backyard solar telescope. This solar storm system did not hurl material toward Earth. Instead, most of the tornado fell back to the sun after an exhausting spin. A higher resolution version of the movie may be found here. 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 June 23, 2022, the network reported 7 fireballs.
(7 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 June 23, 2022 there were 2279 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."
