Near Calgary, Alberta, Harlan Thomas photographed the fall colors on Sept. 23rd: 
"What a way to herald the autumnal equinox!" says Thomas. "It was fantastic to see these beautiful auroras with uniquely colored pink pillars." Thomas captured a phenomenon that sky watchers have known about for centuries, but science has only recently understood. Auroras love equinoxes. At this time of year, colorful lights can appear even without a geomagnetic storm. Researchers call it the "Russell-McPherron effect." During the first weeks of autumn, cracks form in Earth's magnetic field. Even a slight gust of solar wind can slip through to spark auroras. This is exactly what happened on Sept. 23rd in Alberta. Happy Equinox! Aurora alerts: SMS Text. more images: from Karsten Berger of Petkula, Finland; from Todd Salat in southcentral Alaska Realtime Aurora Photo Gallery
Free: Spaceweather.com Newsletter THE SUN SHOOTS LIKE AN IMPERIAL STORM TROOPER: Shoot, shoot. Miss. Yesterday, Sept. 23rd, a pair of bright CMEs left the sun. Both are off target: 
The CME on the right is debris from an exploding magnetic filament. The CME on the left came from new sunspot AR3110; an M1-class solar flare hurled it into space. The bright light at 3 o'clock is Venus. None of these things will hit our planet. The sun can't keep missing forever, can it? Active sunspot AR3110 is turning toward Earth and will soon be in the strike zone. Stay tuned. Aurora alerts: SMS Text. Realtime Space Weather Photo Gallery

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 24, 2022, the network reported 27 fireballs.
(27 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 September 24, 2022 there were 2294 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."
