A final minor CME launched toward Earth by old sunspot AR3078 might indeed graze our planet's magnetic field today. However, it is already late, and thus slow; a tardy impact is unlikely to produce geomagnetic storms. Aurora alerts: SMS Text AURORAS IN THE USA: Last week at least three CMEs hit Earth, none with great force, but together they were sufficient to spark multiple geomagnetic storms. On Aug. 20th, auroras spilled over the Canadian border into Ely, Minnesota: 
"After the cloud deck broke, I was able to watch these beautiful pink pillars roll across the sky," says photographer Greg Ash, located at the end of the dock. "They were very visible to the naked eye." Note: The storms were originally predicted to reach category G3 (strong). Instead they peaked at category G2 (moderate), one notch below. That doesn't mean the forecast was wrong; if only one of the CMEs had been a little more potent, the needle almost certainly would have hit the predicted value. Solar Cycle 25 is just getting started, so there will be a next time. Stay tuned!

Free: Spaceweather.com Newsletter DANCING SPRITES OVER PUERTO RICO: Pro tip for storm chasers: Point your cameras just above the thundercloud. You might see something like this: 
Frankie Lucena photographed the display last night from Cabo Rojo, Puerto Rico. He caught at least half a dozen red sprites leaping up from a powerful thunderstorm offshore: map. "These are dancing sprites," says Lucena. "That's when a sprite event contains multiple sprites that fire up in a sequence. I combined them by stacking 10 video frames to show how impressive this event really was." A slow motion video shows the individual dancers. Realtime Sprite Photo Gallery

At the apex of the flight it floated 101,326 feet above the Sierra Nevada mountains of central California:
You can have it for $142.95. The opal's infinity wrap is engraved with "I Love You More." It's the perfect birthday, anniversary or (never too early!) Christmas gift for that special someone who loves space. Each pendant comes with a greeting card showing the pendant in flight and telling the story of its trip to the stratosphere and back.

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 Aug 24, 2022, the network reported 4 fireballs.
(4 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 August 22, 2022 there were 2288 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."
