SOLAR ACTIVITY ALERT: The odds of an Earth-directed solar flare are increasing as active sunspot 4436 turns toward our planet. On May 10th (1339 UTC) it blew massive hole in the sun's atmosphere during an M5.7-class solar flare: SOHO coronagraphs are tracking the emerging CME. It should be a near miss, passing by Earth on May 13th, according to a NASA model. Ripples from the close encounter might cause geomagnetic distrbances around the poles. The next explosion might not miss. This sunspot has a history: Last week while it was on the farside of the sun it produced at least 5 CMEs. If the serial explosions continue in the days ahead, Earth will be inside the strike zone. Stay tuned. Solar flare alerts: SMS Text COMET PANSTARRS AND THE ORION NEBULA: This weekend, Comet PanSTARRS (C/2025 R3) is passing by M42, the Orion Nebula. Amateur astronomer Marco Nero photographed the encounter from Katoomba, Australia: "The comet itself was just below visible threshold for optical viewing," says Nero. "But it was an easy catch with my camera. The tail is visible even on images from my iPhone." Southern-hemisphere astronomers are encouraged to check out this scene after local sunset. Wide-angle photos with night-sky settings will reveal the comet in only a few seconds of exposure time.

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 May 9, 2026, the network reported 4 fireballs. (3 sporadics, 1 eta Aquariids) 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 May 10, 2026 there were 2349 potentially hazardous asteroids.

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 10 years, resulting in a unique dataset of in situ atmospheric measurements. Latest results (Nov. 2024): Atmospheric radiation is sharply decreasing in 2024. Our latest measurements in November registered a 10-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.
