The northern season for NLCs began on May 26th. The first clouds were detected inside the Arctic Circle by the NOAA 21 satellite. An instrument onboard NOAA 21 (OMPS LP) is able to detect NLCs (also known as "polar mesospheric clouds" or PMCs). For the rest of the season, daily maps from NOAA 21 will be presented here:
Updated: Aug. 29, 2023
Each dot is a detected cloud. As the season progresses, these dots will multiply in number and shift in hue from blue to red as the brightness of the clouds intensifies.
What happened to NASA's AIM spacecraft, which has been monitoring NLCs since 2007? Earlier this year, the spacecraft's battery failed. As a result AIM is offline, perhaps permanently. There may be some hope of a recovery as AIM's orbit precesses into full sunlight in 2024. Until then, we will maintain AIM's iconic "daily daisy," frozen at Feb. 28, 2023, as a show of thanks for years of service and hope for future daisies:  | | | Switch view:Ross Ice Shelf, Antarctic Peninsula, East Antarctica, Polar Updated Nov06 SPACE WEATHER

Two CMEs hit Earth over the weekend--one on Saturday, Nov. 4th, another on Sunday, Nov. 5th. The double blow sparked a strong G3-class geomagnetic storm with auroras as far south as Colorado (+40.1N) and Texas (+33.6N). The storm is now subsiding with isolated periods of minor G1-class storming expected through Nov. 6th. Aurora alerts: SMS Text NOT ALL THE LIGHTS WERE AURORAS: At the apex of the storm, bright lights danced across the skies of northern Europe. Not all the lights were auroras. "To our utter amazement we observed a striking phenomenon," reports Martin McKenna of Swatragh, N. Ireland. "It was STEVE!" 
"We were blown away by the intensity of the purple beam," continues McKenna."We could see it plainly with the naked eye, swelling and flickering in brilliance with delicate structures like those seen within a feather. My mate Conor likened it to a celestial funnel cloud or tornado changing form in real time." STEVE is a recent discovery. It looks like an aurora, but it is not. The soft purple glow is caused by hot (3000°C) rivers of gas flowing through Earth’s magnetosphere at speeds exceeding 6 km/s (13,000 mph). These rivers are energized by strong geomagnetic storms like the one that happened over the weekend. Wil Cheung observed an even more dramatic apparition of STEVE over Whitley Bay, England: 
"It lasted for more than an hour," marvels Cheung. "Strong auroras danced in the north while STEVE flowed through the sky to my south." Although our understanding of STEVE has rapidly progressed over the past few years, there are still many unsolved mysteries about the phenomenon. Every sighting is about 75% enigma.

AMBER DRAGONFLY SPACE PENDANT: This dragonfly has touched space. On Oct 31st, the students of Earth to Sky Calculus launched it to the stratosphere onboard a cosmic ray research balloon, 105,108 feet above California's Sierra Nevada: 
You can have it for $169.95. Made of genuine Baltic Amber with a sterling silver exoskeleton, the rich Cognac-colored pendant measures 3/4 inch and comes with a matching 18-inch sterling silver chain. The students are selling space pendants to pay the helium bill for their cosmic ray ballooning program. Each one comes with a greeting card showing the jewelry in flight and telling the story of its trip to the stratosphere and back again. Far Out Gifts: Earth to Sky Store

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 Nov 05, 2023, the network reported 9 fireballs.
(4 sporadics, 2 Northern Taurids, 2 Orionids, 1 November Draconid)  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 November 6, 2023 there were 2349 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."
