The likely source would be sunspot AR3327, which has an unstable 'delta-class' magnetic field. Any explosions will be geoeffective as the sunspot is almost directly facing Earth. Solar flare alerts: SMS Text SUNSPOTS THROUGH THE SMOKE: Elon Musk wants to go to Mars. Canada is a lot closer. Smoke from Canadian wildfires is turning skies across northeastern provinces and US states the color of the Red Planet. One side effect of the rusty gloom is the sudden visibility of sunspots. "Smoke has filtered the sun an eerie orange color on and off for weeks here along the East Coast," reports Neil Winston of Calvert County, Maryland. "As the sun dips low in the sky, it has made an opportunity to image the numerous sunspots without a solar filter." "It is still not safe to view the sun directly, even through smoke, as the brightness remains a hazard," Winston cautions. "I took this picture with my mirrorless camera using the digital screen to view and focus." (Photo settings here.) Wildfires in Canada and the western United States have become routine in recent summers. These, however, are unusual. “Outbreaks as widespread and numerous as these are virtually unheard of in late May into June," according to the Capital Weather Gang. "The amount of smoke pouring into the northeastern USA is thus also exceptional." More than 75 million people are under air-quality alerts as Martian skies are expected to continue throughout the weekend. more images: from Joseph Golebieski of Lavallette, NJ; from Alan Friedman of Buffalo, NY; from Elaine Parker of Westover, Maryland; from Mike Schatz of Jarrettsville, MD; Realtime Space Weather Photo Gallery Free: Spaceweather.com Newsletter FAR OUT FATHER'S DAY GIFT: It's Capt. Kirk's favorite flask! Inscribed with the words "To Boldly Go Where No One Has Gone Before," this sterling silver container flew to the stratosphere on June 4, 2023, onboard an Earth to Sky Calculus cosmic ray research balloon: You can have it for $122.95. During the flight, the flask experienced temperatures as low as -59 C. It was still cold to the touch when students retrieved it 30 minutes after landing in Pine Creek Canyon in the Sierra Nevada mountains near Bishop CA. The flask comes with a greeting card showing itself in flight, and telling the story of its journey to the stratosphere and back again. It makes a great Father's Day gift for Trekkie dads!

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 Jun 08, 2023, the network reported 10 fireballs. (10 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 June 8, 2023 there were 2335 potentially hazardous asteroids. | Recent & Upcoming Earth-asteroid encounters: Asteroid | Date(UT) | Miss Distance | Velocity (km/s) | Diameter (m) | 2023 JE5 | 2023-Jun-04 | 17.6 LD | 8 | 35 | 2023 JR2 | 2023-Jun-04 | 17 LD | 7.6 | 38 | 2023 HO18 | 2023-Jun-04 | 1.2 LD | 4.7 | 29 | 2023 LB | 2023-Jun-05 | 5.9 LD | 19.9 | 47 | 2023 KW2 | 2023-Jun-06 | 11.8 LD | 10.1 | 65 | 2023 LC | 2023-Jun-07 | 0.7 LD | 4.4 | 7 | 2018 KR | 2023-Jun-07 | 6.5 LD | 4.9 | 19 | 2017 UJ2 | 2023-Jun-07 | 5.3 LD | 5.6 | 2 | 2023 LD | 2023-Jun-09 | 2.5 LD | 9.1 | 19 | 2023 JB3 | 2023-Jun-09 | 14.1 LD | 6.9 | 52 | 2023 LA | 2023-Jun-12 | 1.7 LD | 10.4 | 32 | 488453 | 2023-Jun-12 | 8.3 LD | 21.5 | 495 | 2022 WN4 | 2023-Jun-13 | 10.8 LD | 15.1 | 158 | 2020 DB5 | 2023-Jun-15 | 11.3 LD | 9.5 | 506 | 2023 HL | 2023-Jun-17 | 13.5 LD | 1 | 15 | 2016 LK49 | 2023-Jun-19 | 17.4 LD | 19.4 | 22 | 2023 HF1 | 2023-Jun-21 | 12.5 LD | 4.4 | 59 | 467336 | 2023-Jun-24 | 17.4 LD | 7.1 | 269 | 2008 LG2 | 2023-Jun-24 | 10.5 LD | 5.6 | 32 | 2013 WV44 | 2023-Jun-28 | 9.1 LD | 11.8 | 95 | 2022 MM1 | 2023-Jun-29 | 9.5 LD | 9.8 | 41 | 2020 NC | 2023-Jul-02 | 13.9 LD | 7.7 | 123 | 2023 HO6 | 2023-Jul-05 | 5.3 LD | 7.8 | 237 | 2019 LH5 | 2023-Jul-07 | 14.9 LD | 21.6 | 281 | 2018 NW | 2023-Jul-10 | 18 LD | 21.8 | 10 | 2018 UY | 2023-Jul-12 | 7.4 LD | 16.4 | 243 | 2020 UQ3 | 2023-Jul-18 | 3.2 LD | 9.3 | 59 | 2022 GX2 | 2023-Jul-20 | 11.9 LD | 9.4 | 5 | 2020 OM | 2023-Jul-20 | 8.5 LD | 9.5 | 14 | 2015 MA54 | 2023-Jul-24 | 16.6 LD | 9.2 | 31 | 2018 BG5 | 2023-Jul-27 | 10.7 LD | 8.4 | 56 | 2020 PP1 | 2023-Jul-29 | 17 LD | 4.1 | 17 | 2021 BD3 | 2023-Jul-30 | 14 LD | 8.5 | 25 | 2016 AW65 | 2023-Jul-31 | 16.6 LD | 5.7 | 54 | 2020 PN1 | 2023-Aug-03 | 10.8 LD | 4.8 | 29 | 620082 | 2023-Aug-04 | 14 LD | 20.6 | 375 | 2004 KG1 | 2023-Aug-06 | 18.7 LD | 9.2 | 54 | Notes: LD means "Lunar Distance." 1 LD = 384,401 km, the distance between Earth and the Moon. 1 LD also equals 0.00256 AU. | Cosmic Rays in the Atmosphere | SPACE WEATHER BALLOON DATA: Almost once a week, Spaceweather.com and the students of Earth to Sky Calculus fly space weather balloons to the stratosphere over California. 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."
