A number of controversial studies ( #1, #2, #3, #4) go even further, linking cosmic rays with cardiac arrhythmias and sudden cardiac death. The researchers listed cosmic rays, irregular sleep habits, and chemical contaminants as leading risk factors. Chan school of public health, crews of aircraft have higher rates of cancer than the general population. According to a study from the Harvard T.H. They can alter the chemistry of the atmosphere, trigger lightning, and penetrate commercial airplanes. Who cares? Cosmic rays are a surprisingly "down to Earth" form of space weather. 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. The sun's strengthening and increasingly tangled magnetic field repels cosmic rays from deep space. Solar Cycle 25 has roared to life faster than forecasters expected. What's going on? Ironically, the radiation drop is caused by increasing solar activity. Our latest measurements in July 2022 registered a 6-year low: Latest results (July 2022): Atmospheric radiation is decreasing in 2022. Our monitoring program has been underway without interruption for 7 years, resulting in a unique dataset of in situ atmospheric measurements. 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. SPACE WEATHER BALLOON DATA: Almost once a week, and the students of Earth to Sky Calculus fly space weather balloons to the stratosphere over California. "Lunar Distance." 1 LD = 384,401 km, the distanceīetween Earth and the Moon. The moonstone comes with a greeting card showing the pendant in flight, telling the story of its trip to the edge of space and back again.Īll sales support hands-on STEM education The moonstone's sterling silver infinity wrap is inscribed with the words "I love you forever." It makes a great anniversary, Christmas or birthday gift. This one hitched a ride to the stratosphere onboard a cosmic ray research ballooin on Oct. "I LOVE YOU FOREVER" MOONSTONE PENDANT: Are you looking for a far-out gift? Consider the "I Love You Forever" Moonstone. And, of course, if anyone saw a rocket, let us know! Photos from different locations may help determine the height of the emission. Any photographers who caught it are encouraged to submit their images. Multiple witnesses in Abisko agree that nothing streaked across the sky before the blue band appeared.įor now, the blue ribbon remains a mystery. Rocket exhaust has been known to create displays like this in the past. 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.

"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." "It looks really odd if it's aurora," he says. Space physicist Toshi Nishimura of Boston University took a look at the video. The whole time, regular green auroras danced around and seemingly in front of it: movie. It rapidly brightened to naked-eye visibility, then sank below the horizon 30 minutes later. Webcams saw it first at 1615 UT (5:15 p.m. One of his tour guides, Miguel Such, video-recorded the phenomenon:Ī G1-class geomagnetic storm was underway on Nov. "It didn't look like any auroras I have ever seen before," says Chad Blakley, the director of Lights over Lapland. MYSTERIOUS BLUE "AURORAS" OVER SWEDEN: Yesterday in Sweden, sky watchers were puzzled when a strange ribbon of blue light appeared during a geomagnetic storm. Yesterday, the same stream sparked spectacular pink auroras inside the Arctic Circle. The gaseous material is flowing from an equatorial hole in the sun's atmosphere. 4th and 5th as Earth continues to pass through a stream of fast-moving solar wind. Neutron counts from the University of Oulu's Sodankyla Geophysical Observatory show that cosmic rays reaching Earth are slowly declining-a result of the yin-yang relationship between the solar cycle and cosmic rays.ĬHANCE OF STORMS TODAY: NOAA forecasters say there is a chance of G1-class geomagnetic storms on Nov. Credit: SDO/HMIĬosmic Rays Solar Cycle 25 is beginning, and this is reflected in the number of cosmic rays entering Earth's atmosphere. All of today's sunspots have stable magnetic fields that pose almost no threat for strong solar flares.
