Cosmic Rays Solar minimum is underway. The sun's magnetic field is weak, allowing extra cosmic rays into the solar system. Neutron counts from the University of Oulu's Sodankyla Geophysical Observatory show that cosmic rays reaching Earth in 2019 are near a Space Age peak.

DEEP SOLAR MINIMUM: As of today, the sun has been blank (no sunspots) 74% of the time in 2019. This is significant because the previous record for spotlessness during the Space Age was 73% set in 2008. If low sunspot counts continue apace, 2019 could end up as the deepest Solar Minimum of the modern era.

FOR NO PARTICULAR REASON, AURORAS AT SEA: Geomagnetic storms and auroras go together. Northern Lights are the telltale glow of Earth's magnetic field vibrating in response to solar wind. So how do we explain this? There was no geomagnetic storm on October 16th when bright auroras appeared off the coast of Tromsø, Norway. Alan Dyer photographed the display from the deck of the ferry ship Trollfjord:

"Despite the fact that geomagnetic activity was low, we had a crowd-pleasing show of Northern Lights from our position in the Norwegian Sea north of Tromsø," says Dyer. "While the purpose of the ferry is to deliver people, cars and cargo, the majority of passengers are sightseers sailing the coast for the spectacular scenery by day and the frequent auroras by night."

So where do the auroras come from? The seas around Tromsø are located beneath Earth's persistent auroral oval. A gentle rain of solar wind electrons, guided to Earth by our planet's curved magnetic field creates a polar ring of Northern Lights that intersects the latitude of Tromsø. Auroras appear there most nights--no geomagnetic storm required. Aurora alerts: SMS Text.

THE SHOOTING STAR PENDANT: It's simple. It's elegant. And it's been to the edge of space. On Sept. 27th, the students of Earth to Sky Calculus launched a cosmic ray balloon to the stratosphere. This stainless steel "shooting star" pendant hitched a ride, all the way to 108,245 feet:

You can have it for $129.95. The students are selling shooting star pendants to support their cosmic ray ballooning program. Each one comes with greeting card showing the item in flight and telling the story of its journey to the edge of space and back again. These make great birthday and Christmas gifts.

Bonus: The star contains a hidden chamber, which you may fill with the ashes of a loved one or anything else you wish to keep close to your heart.

  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 Oct. 18, 2019, the network reported 33 fireballs.
(29 sporadics, 3 southern Taurids, 1 Orionid)

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 October 18, 2019 there were 2018 potentially hazardous asteroids.

  Cosmic Rays in the Atmosphere

SOMETHING NEW! We have developed a new predictive model of aviation radiation. It's called E-RAD--short for Empirical RADiation model. We are constantly flying radiation sensors onboard airplanes over the US and and around the world, so far collecting more than 22,000 gps-tagged radiation measurements. Using this unique dataset, we can predict the dosage on any flight over the USA with an error no worse than 15%.

E-RAD lets us do something new: Every day we monitor approximately 1400 flights criss-crossing the 10 busiest routes in the continental USA. Typically, this includes more than 80,000 passengers per day. E-RAD calculates the radiation exposure for every single flight.

The Hot Flights Table is a daily summary of these calculations. It shows the 5 charter flights with the highest dose rates; the 5 commercial flights with the highest dose rates; 5 commercial flights with near-average dose rates; and the 5 commercial flights with the lowest dose rates. Passengers typically experience dose rates that are 20 to 70 times higher than natural radiation at sea level.

To measure radiation on airplanes, we use the same sensors we fly to the stratosphere onboard Earth to Sky Calculus cosmic ray balloons: neutron bubble chambers and X-ray/gamma-ray Geiger tubes sensitive to energies between 10 keV and 20 MeV. These energies span the range of medical X-ray machines and airport security scanners.

Column definitions: (1) The flight number; (2) The maximum dose rate during the flight, expressed in units of natural radiation at sea level; (3) The maximum altitude of the plane in feet above sea level; (4) Departure city; (5) Arrival city; (6) Duration of the flight.

SPACE WEATHER BALLOON DATA: Approximately 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 radiation sensors that detect cosmic rays, a surprisingly "down to Earth" form of space weather. Cosmic rays can seed clouds, trigger lightning, and penetrate commercial airplanes. Furthermore, there are studies ( #1, #2, #3, #4) linking cosmic rays with cardiac arrhythmias and sudden cardiac death in the general population. Our latest measurements show that cosmic rays are intensifying, with an increase of more than 18% since 2015:

The data points in the graph above correspond to the peak of the Reneger-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 Reneger and Georg Pfotzer discovered the maximum using balloons in the 1930s and it is what we are measuring today.

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 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.

Why are cosmic rays intensifying? The main reason is the sun. Solar storm clouds such as coronal mass ejections (CMEs) sweep aside cosmic rays when they pass by Earth. During Solar Maximum, CMEs are abundant and cosmic rays are held at bay. Now, however, the solar cycle is swinging toward Solar Minimum, allowing cosmic rays to return. Another reason could be the weakening of Earth's magnetic field, which helps protect us from deep-space radiation.
