Cosmic Rays Solar Cycle 25 is beginning, 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.

BIG SUNSPOT ALERT: A second large sunspot is emerging over the sun's southeastern limb, joining AR3105, which itself has doubled in size since yesterday. If you have a solar telescope, point your optics here. Solar flare alerts: SMS Text.

AN EXPLOSION OF AURORAS OVER NORWAY: Last night in Tromsø, Norway, there was an explosion of auroras so intense "it made my guests scream and laugh at the same time," says aurora tour guide Markus Varik. "We had no idea the night would turn out like this!"

"There were swirls, spikes, curtains, draperies, you name it," says Varik. "We must be getting close to the equinox."

Indeed, that's exactly what's happening. The northern autumnal equinox is only 3 days away and, as all Arctic sky watchers know, auroras love equinoxes.

Researchers call it the "Russell-McPherron effect." During the weeks around equinoxes, cracks form in Earth's magnetic field. Even a slight gust of solar wind can slip through to spark a light show--no geomagnetic storm required.

Stay tuned for more outbursts of light as autumn approaches. Aurora alerts: SMS Text.

COSMIC RAY YIN-YANG PENDANT: To celebrate the yin-yang relationship between solar activity and galactic cosmic rays, the students of Earth to Sky Calculus just launched a yin-yang pendant to the stratosphere. Here it is, flying 104,265 ft high onboard a cosmic ray research balloon:

You can have it for $142.95. The pendant's sterling silver frame surrounds balancing swirls of black onyx and mother of pearl--all suspended from a matching 18-inch sterling silver chain. It makes a great anniversary, birthday or (never too early!) Christmas gift.

The students are selling yin-yang pendants to support their cosmic ray ballooning program. Each one comes with a greeting card showing the pendant in flight and telling the story of its journey to the edge of space and back again.

  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 Sep 20, 2022, the network reported 24 fireballs.
(21 sporadics, 2 southern Taurids, 1 Sept. epsilon Perseid)

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 September 20, 2022 there were 2294 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.
