Cosmic Rays Solar Cycle 25 is intensifying, and this is reflected in the number of cosmic rays entering Earth's atmosphere. Neutron counts from the University of Oulu's Sodankyla Geophysical Observatory show that cosmic rays reaching Earth are slowly declining--a result of the yin-yang relationship between the solar cycle and cosmic rays.

Polar Stratospheric Clouds
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.

GEOMAGNETIC STORM WATCH (G1): Minor G1-class geomagnetic storms are possible on Nov. 7th when a CME is expected to hit Earth's magnetic field. NOAA and NASA models agree that the flank of the CME will only 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

STRONG FLARES ARE UNDERWAY (UPDATED): Solar activity has reached high levels on Nov. 6th as sunspots AR3883 and AR3886 crackle with strong solar flares. The most powerful so far is this X2-class explosion centered on AR3883:

Extreme UV radiation is ionizing the top of Earth's atmosphere, causing shortwave radio blackouts. Ham radio operators DXing across the southern hemisphere may notice intermittent loss of signal below 30 MHz.

Update: So far there is no sign of a significant CME emerging from today's explosions. However, more data from SOHO coronagraphs are required to confirm. Stay tuned. Solar flare alerts: SMS Text

  All Sky Fireball Network
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 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]
  Near Earth Asteroids
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.

  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 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.
