Colorful Type II polar stratospheric clouds (PSC) form when the temperature in the stratosphere drops to a staggeringly low -85C. NASA's MERRA-2 climate model predicts when the air up there is cold enough: 
On Nov. 05, 2024, the Arctic stratosphere is cooling but still too warm for Type II polar stratospheric clouds. | more data. Noctilucent Clouds
The northern season for NLCs is underway--but not for long. The first clouds were detected inside the Arctic Circle on May 25, 2024, by the NOAA 21 satellite. After peaking in July, the clouds are now in rapid decline. This is typical for the month of August, which usually brings the end of NLC season in the northern hemisphere.
Updated: Aug. 28, 2024
An instrument onboard NOAA 21 (OMPS LP) is able to detect NLCs (also known as "polar mesospheric clouds" or PMCs). In the daily map, above, 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.

NOAA and NASA models agree that the flank of the CME will, at most, graze our planet's magnetosphere. In fact, a miss is just as likely as a hit, making this a low probability forecast. CME impact alerts: SMS Text THE SUN IS CRACKLING WITH FLARES: A phalanx of southern sunspots is turning toward Earth, and they are crackling with solar flares. During the past 24 hours, Earth-orbiting satelites have detected multiple M-class flares and one intense X-flare: 
Pulses of extreme ultraviolet radiation are ionizing the top of Earth's atmosphere, causing a series of shortwave radio blackouts rolling around all longitudes of our planet. Ham radio operators may notice intermittent loss of signal at frequencies below below 30 MHz. So far, none of the explosions has produced a significant CME. This could change in response to more explosions later today. Stay tuned. Solar flare alerts: SMS Text Realtime Space Weather Photo Gallery

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 06, 2024, the network reported 22 fireballs.
(20 sporadics, 1 northern Taurid, 1 omicron Eridanid)  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 7, 2024 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."
