On Jan. 3rd it produced a probable X-class eruption on the farside of the sun, followed on Jan. 6th by a definite X-flare on the Earthside. Given the size and apparent complexity of this large active region, there's a good chance the explosions will continue in the days ahead. Solar flare alerts: SMS Text. X-CLASS SOLAR FLARE: Sunspot AR3182 is living up to the hype. Fully visible for less than 24 hours, the active sunspot has already produced an intense X1.2-class solar flare. NASA's Solar Dynamics Observatory recorded the eruption on Jan. 6th just before 0100 UT: 
The explosion inflated a dome of glowing-hot plasma, which hovered above the blast site for more than an hour. This may have contained the debris. So far no coronal mass ejection (CME) has been observed emerging from the area. A pulse of X-rays and extreme UV radiation from the flare ionized the top of Earth's atmosphere, causing a shortwave radio blackout across South Pacific: 
Ham radio operators, mariners and aviators may have noticed unusual propagation effects at frequencies below 30 MHz for as much as an hour after the flare. Solar flare alerts: SMS Text. Realtime Space Weather Photo Gallery

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 Jan 06, 2023, the network reported 11 fireballs.
(10 sporadics, 1 Dec. Leonis Minorid)  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 January 6, 2023 there were 2324 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."
