The gaseous material is flowing from an equatorial hole in the sun's atmosphere. Yesterday, the same stream sparked spectacular pink auroras inside the Arctic Circle. Aurora alerts: SMS Text. MYSTERIOUS BLUE "AURORAS" OVER SWEDEN: Yesterday in Sweden, sky watchers were puzzled when a strange ribbon of blue light appeared during a geomagnetic storm. "It didn't look like any auroras I have ever seen before," says Chad Blakley, the director of Lights over Lapland. One of his tour guides, Miquel Such, video-recorded the phenomenon: A G1-class geomagnetic storm was underway on Nov. 3rd when the blue ribbon appeared. Webcams saw it first at 1615 UT (5:15 p.m. local Abisko time). It rapidly brightened to naked-eye visibility, then sank below the horizon 30 minutes later. The whole time, regular green auroras danced around and seemingly in front of it: movie. But what was it? Space physicist Toshi Nishimura of Boston University took a look at the video. "It looks really odd if it's aurora," he says. "One auroral arc shouldn't cut across another auroral arc without disturbing it, so it's hard to explain this from an auroral physics point of view."

Since late October Russia has been conducting ICBM firing exercises in the Barents Sea with the nuclear-powered missile cruiser "Peter the Great" in the area for combat training. Rocket exhaust has been known to create displays like this in the past. However, no one saw a rocket. Multiple witnesses in Abisko agree that nothing streaked across the sky before the blue band appeared. For now, the blue ribbon remains a mystery. Any photographers who caught it are encouraged to submit their images. Photos from different locations may help determine the height of the emission. And, of course, if anyone saw a rocket, let us know! more images: from Hendrik Zwart of Sjøvegan, Salangen Kommune, Norway Realtime Aurora Photo Gallery Free: Spaceweather.com Newsletter "I LOVE YOU FOREVER" MOONSTONE PENDANT: Are you looking for a far-out gift?

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 Nov 04, 2022, the network reported 41 fireballs.

The orbits are color-coded by velocity, from slow (red) to fast (blue).

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."
