Today there is a 40% chance of M-class flares and a 5% chance of X-flares, according to NOAA. Solar flare alerts: SMS Text STARLINER REACHES THE ISS: Boeing's Starliner spacecraft has finally reached the International Space Station (ISS). Szabolcs Nagy of London, England, photographed the capsule just before docking on Friday, May 20th: "Boeing's Starliner was only 200 meters from the ISS," says Nagy, who manually tracked the pair using a 10-inch dobsonian telescope. "Seeing them so close together was an incredible experience. Just wow!!" Soon after its London flyby, the nose of the Starliner latched onto one of the space station's docking ports. Space station crewmembers opened the hatch on Saturday, May 21st, and started unloading 800 pounds of cargo, mostly food and supplies. The only astronaut on board was a test dummy--Rosie the Rocketeer, who rode in the captain's chair. Rosie was outfitted with 15 sensors to collect data on what real astronauts will experience during future flights on Starliner. Boeing has been trying to reach the ISS for years. Starliner's first test flight in 2019 failed to reach the space station. The company spent the next two and a half years fixing technical problems. Meanwhile, SpaceX raced ahead, carrying 5 crews to the ISS onboard its Crew Dragon spacecraft. Starliner's successful launch from Cape Canaveral on May 19th signals that Boeing, too, is in the New Space Race. If all goes as planned, Starliner could taxi crews as large as seven to the ISS by the end of 2022.

This one hitched a ride to the stratosphere onboard a cosmic ray research balloon on May 13, 2022: You can have it for $159.95. At the apex of the flight, the hummingbird floated 112,336 feet above the snow-capped Sierra Nevada mountains while sensors in the payload measured cosmic rays. It makes a great anniversary or birthday gift. The hummingbird comes with a greeting card showing the pendant in flight, telling the story of its trip to the edge of space and back again. Bonus: The pendant contains a tiny chamber, which you may fill with the ashes of a loved one or anything else you wish to keep close to your heart.

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 May 22, 2022, the network reported 2 fireballs. (2 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 May 22, 2022 there were 2279 potentially hazardous asteroids. | Recent & Upcoming Earth-asteroid encounters: Asteroid | Date(UT) | Miss Distance | Velocity (km/s) | Diameter (m) | 2013 UX | 2022-May-17 | 16.8 LD | 16.3 | 141 | 2022 KG | 2022-May-18 | 6.9 LD | 9.2 | 26 | 2021 WY | 2022-May-18 | 16.9 LD | 9 | 65 | 2022 JQ1 | 2022-May-19 | 11.5 LD | 4.9 | 22 | 2022 HD1 | 2022-May-20 | 15.3 LD | 6.8 | 60 | 2022 KH | 2022-May-22 | 3.8 LD | 15.8 | 29 | 2013 KS1 | 2022-May-24 | 2.6 LD | 9.3 | 16 | 2022 KJ | 2022-May-24 | 9.6 LD | 14.2 | 22 | 2022 KK | 2022-May-25 | 1.4 LD | 14.2 | 14 | 7335 | 2022-May-27 | 10.5 LD | 13.1 | 1078 | 2022 JU1 | 2022-May-27 | 15.1 LD | 6.1 | 37 | 2022 KA | 2022-May-28 | 14.8 LD | 8.6 | 32 | 2022 JY | 2022-May-28 | 15.1 LD | 10.9 | 67 | 2021 KO2 | 2022-May-30 | 3.1 LD | 14.8 | 9 | 2022 HT2 | 2022-May-30 | 11.9 LD | 15.7 | 224 | 2020 DA4 | 2022-Jun-01 | 5.5 LD | 8.9 | 26 | 2021 GT2 | 2022-Jun-06 | 9.5 LD | 7.5 | 50 | 2018 LU2 | 2022-Jun-09 | 14.8 LD | 10.7 | 16 | 2006 XW4 | 2022-Jun-12 | 5.9 LD | 7.3 | 49 | 2022 GU6 | 2022-Jun-12 | 3.2 LD | 8.4 | 88 | 2015 WP2 | 2022-Jun-26 | 18.5 LD | 11.4 | 3 | 2022 JE1 | 2022-Jul-03 | 8.6 LD | 5.6 | 74 | 2021 EL4 | 2022-Jul-05 | 19.8 LD | 9.5 | 25 | 2015 OQ21 | 2022-Jul-12 | 18.3 LD | 6.6 | 9 | 2021 OT | 2022-Jul-17 | 16.5 LD | 11.2 | 20 | 349068 | 2022-Jul-19 | 17.6 LD | 22.9 | 756 | Notes: LD means "Lunar Distance." 1 LD = 384,401 km, the distance between Earth and the Moon. 1 LD also equals 0.00256 AU.

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."
