You can, too! | | | NO CME THIS TIME: Yesterday's X1.9-class solar flare did not hurl a CME toward Earth. Although it was intense, the blast was too brief to lift a CME out of the sun's atmosphere. Next time may be different. There are now three large sunspots (AR3181, 82 and 84) with unstable 'delta-class' magnetic fields capable of strong explosions. NOAA forecasters say there is a 35% chance of X-flares on Jan. 10th. X-flare alerts: SMS Text. X-CLASS SOLAR FLARE: Yesterday in Kentucky, amateur astronomer Richard Schrantz was scanning the sun with his solar telescope when, almost finished, he decided to take one last look at sunspot AR3184. "What luck!" he says. "There was a big X1.9 solar flare in progress." 
"The flare is listed as happening at 18:50 UT, and my image is just a few minutes later at 18:55 UT," says Schrantz. "To capture the eruption I used a 127mm refracting telescope with a Daystar Quark Chromosphere filter." Right now, the sun is so active it is possible to catch X-flares by accident. Success rates may be further improved by instant text alerts when flares are in progress. more images: from Laurie Sibbald of Cypress County, Alberta; from Sylvain Weiller of Jerusalem, Israel Realtime Space Weather Photo Gallery
Free: Spaceweather.com Newsletter SOLAR FLARE CAUSES RARE 'MAGNETIC CROCHET': The X-flare of Jan. 9th did something rare. It jerked Earth's magnetic field. Here is a composite of magnetometer recordings from Boulder, Colorado; Honolulu, Hawaii; and Fredericksburg, Virginia:  Full recordings: FRD, BOU, HON. Credit: International Real-time Magnetic Observatory Network (INTERMAGNET)
The "jerk" is circled in yellow. It began around 1846 UT, and was detected by many magnetic observatories across the dayside of Earth. The phenomenon is called a 'magnetic crochet.' Radiation from the flare ionized the top of Earth's atmosphere and caused currents to flow 60 km to 100 km above Earth's surface. These currents, in turn, briefly altered Earth's magnetic field. Everything returned to normal a few minutes later. 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 10, 2023, the network reported 13 fireballs.
(11 sporadics, 1 Quadrantid, 1 theta Coronae Borealid)  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 10, 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."
