'CANYON OF FIRE' OPENS, SPITS A CME TOWARD EARTH: Yesterday, Nov. 5th, a filament of magnetism in the sun's northern hemisphere became unstable and erupted. The blast split the sun's atmosphere, hurling a CME into space and creating a "canyon of fire," shown here in a movie recorded by the Solar Dynamics Observatory:

The glowing walls of the canyon trace the original channel where the filament was suspended by magnetic forces above the sun's surface. From end to end, the structure stretches more than 200,000 km--a real Grand Canyon.

Fragments of the exploding filament formed the core of a CME that raced away from the sun faster than a million mph: movie. NOAA analysts have modeled the trajectory of the CME and concluded that it will probably strike Earth's magnetic field on Nov. 8th. The impact could spark G1-class geomagnetic storms and auroras at high latitudes. Free: Aurora Alerts

AIRGLOW IN THE POLAR NIGHT: "Polar night is coming to the subarctic," reports Mia Stålnacke of Kiruna, Sweden, just inside the Arctic Circle. "The sun set at 2:36 p.m. yesterday and at around 7:30 p.m. I shot this."

Stålnacke's long exposure captured not only the Milky Way looming over Kiruna, but also a beautiful splash of green.

Inside the Arctic Circle, green is normally a sign of geomagnetic activity--that is, the aurora borealis. "But this was no aurora," she says. "It's airglow."

Airglow is a chemical reaction involving oxygen in the upper atmosphere driven in part by solar ultraviolet radiation and cosmic rays.  Visibility waxes and wanes with conditions such as pressure and temperature in the rarified air more than 90 km above Earth's surface. Gravity waves traveling up from the planet below impress the verdant glow with a dramatic rippling structure.

Dark nights with a new or thin crescent Moon are the best times to catch a glimpse of airglow. Often, the glow is dim and pale to the naked eye, revealing its green color only to the lens of cameras set for Milky Way-length exposures. Seeing airglow above the Arctic Circle is even more challenging as it is frequently overwhelmed by the brighter glow of auroras. Stålnacke picked a rare night when auroras were absent. As her photo shows, however, the polar night is never truly free of wonders.

THE CANIGOU EFFECT: On the evening of Nov. 1st, J.P. Pettit watched the sunset from Marseille, France. As the fiery solar disk sank into the waters of the Mediterranean Sea, a jagged mountain thrust up in front of the sun ... "which is strange," says Pettit, "because there are no mountains sticking out of the Mediterranean." So he took this picture to document the apparition:

Indeed, there are no mountains in the Mediterranean, but there are mountains 165 miles away in the Pyrenees.  "Pettit witnessed the 'Canigou Effect'," explains atmospheric optic expert Les Cowley. "This is the silhouette of the Pyrenees' Canigou Massif."

"There is no direct line of sight to the Massif because of the Earth's curvature," continues Cowley. "The view is only possible because light is refracted around Earth. Basically, the atmosphere is denser at lower levels and acts like a lens to bend sun rays around the horizon. Mirages can do the same thing, but a mirage was not needed here – just steady and clean air and a long stretch of sea."

"What an incredible special effect," says Pettit.  "Just WOW!"

"This is not a chance observation," adds Cowley. "Alain Origne has made a systematic study of the phenomenon and predicts when it will occur. He would like to hear of other long distance sightings."

  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

On Nov. 6, 2016, the network reported 17 fireballs.
(14 sporadics, 3 Northern Taurids)

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 6, 2016 there were potentially hazardous asteroids.

  Cosmic Rays in the Atmosphere

Readers, thank you for your patience while we continue to develop this new section of We've been working to streamline our data reduction, allowing us to post results from balloon flights much more rapidly, and we have developed a new data product, shown here:

This plot displays radiation measurements not only in the stratosphere, but also at aviation altitudes. 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. These measurements are made by our usual cosmic ray payload as it passes through aviation altitudes en route to the stratosphere over California.

What is this all about? Approximately once a week, 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 12% since 2015:

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.

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.

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.
