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.

GEOMAGNETIC STORM IN PROGRESS: A minor G1-class geomagnetic storm is in progress on Nov. 30th as Earth enters a slow-moving but strongly magnetized stream of solar wind. This might be a co-rotating interaction region (CIR)--a shock-like boundary zone between slow and fast-moving solar wind. CIRs often do a good job sparking high latitude auroras. Aurora alerts: SMS Text.

ANDROMEDID METEOR OUTBURST: The Andromedids are back. Over the weekend astronomers reported an outburst of more than 100 faint meteors per hour. "[It was] the strongest outburst of Andromedid meteors ever detected by the Canadian Meteor Orbit Radar (CMOR)," says Peter Brown of the University of Western Ontario. This radar sky map shows a hot spot of meteor activity on Nov. 28th:

The shower's not over yet. "The current outburst is ongoing and it may be another few days or even a week before the activity ramps down," says Brown. "These meteors are too faint to see with the naked eye, but they are easy targets for our radar."

Andromedids are debris from Biela's Comet, known to historians as "the comet that split in two." 3D/Biela started to fall apart not long after it was discovered in 1772. It was a double comet when it swung by Earth in 1852 and, after that, was never seen again. In 1872 and 1885, thousands of meteors shot out of the constellation Andromeda as Earth passed through Biela's remains. Chinese records described "stars that fell like rain."


Above: Andromedids on the night of November 27, 1872, by Amédée Guillemin [ref]

Then the Andromedids vanished, too. The shower has been weak or absent entirely since the late 19th century. Only a surprise outburst in 2011 signaled that Biela's debris might still be lurking nearby. This week's activity is even more promising.

Bill Cooke of NASA's Meteoroid Environment Office (MEO) is one of several experts who have been modeling Biela's debris streams, hoping to forecast a return. "Our models generally do not do well in predicting the timing or intensity," he says. "However, this year our model got the timing roughly correct." This plot shows current radar data (red dots) vs. predicted debris stream crossings:

According to Cooke's model, the outburst on Nov. 28th was caused by a stream of dust laid down in 1655--interestingly before the comet fell apart. "We didn't think the 1655 crossing would produce much of anything," confesses Cooke. "So the outburst came as a bit of a surprise."

A team of astronomers led by Paul Wiegert (including Brown) had already predicted a strong naked-eye Andromedid outburst in December 2023. If they are right, the display two years from now could yield as many as 200 bright meteors an hour, surpassing even the Perseids and Geminids. The current outburst is providing new data for their stream models, and could help improve the predictions.

Stay tuned for updates as the shower continues.

Note: The Canadian Meteor Orbit Radar is operated through a cooperative agreement between Western University’s Meteor Physics Group and NASA’s Meteoroid Environment Office.

  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 30, 2021, the network reported 34 fireballs.
(32 sporadics, 2 Nov. omega Orionids)

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 30, 2021 there were 2241 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 6 years, resulting in a unique dataset of in situ atmospheric measurements.

Latest results: Our most recent flight on June 25, 2021, confirms a trend of decreasing cosmic radiation:

Cosmic ray dose rates peaked in late 2019, and have been slowly declining ever since. This makes perfect sense. Solar Minimum was in late 2019. During Solar Minimum the sun's magnetic field weakens, allowing more cosmic rays into the solar system. We expect dose rate to be highest at that time.

Now that Solar Minimum has passed, the sun is waking up again. Solar magnetic fields are strengthening, providing a stiffer barrier to cosmic rays trying to enter the solar system. The decline of cosmic radiation above California is a sign that new Solar Cycle 25 is gaining strength.

.Who cares? Cosmic rays are a surprisingly "down to Earth" form of space weather. They can seed clouds, 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. Somewhat more controversial studies (#1, #2, #3, #4) llink cosmic rays with cardiac arrhythmias and sudden cardiac death.

En route to the stratosphere, our sensors also pass through aviation altitudes:

In this plot, dose rates are expessed as multiples of sea level. For instance, we see that boarding a plane that flies at 25,000 feet exposes passengers to dose rates ~10x higher than sea level. At 40,000 feet, the multiplier is closer to 50x. The higher you fly, the more radiation you will absorb.

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 first graph ("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.
